Arduino code generator

This tutorial shows how to make a simple waveform generator using the Arduino and the DAC features of the Arduino Due board. With push buttons, you will be able to choose a waveform shape sine, triangular, sawtooth, or square on both DAC channels and change the frequency of the generated signal. Connect power and ground on your breadboard to the Arduino.

In the image below, the red power and black ground wires connect to the two long vertical rows on the breadboard, providing access to 3. Connect a wire from digital pin 2 to one leg of a pushbutton. That same leg of the button connects through a pull-down resistor kilohm to ground. The other leg of the button connects to the 3. Hook up the potentiometer by connecting one side to power and the other side to ground.

The pin in the middle of the potentiometer goes to analog input 0. The waveforms are stored inside a two-dimensional array where each row represent a different waveform shape. The waveform samples are contained inside the columns, so you can access the waveform table using two indexes:. With the waveformIndex array, you choose which samples to read. By incrementing the sampleIndex array from 0 to the maximum in a fixed time, you will create the waveform shape.

Repeating this procedure continuously and sending the samples values on the DAC output will give you a constant signal. In order to choose the waveform shape with a push button, match the button press to the waveformIndex increment. So, when the Arduino Due sees a rising edge on the button pin, it will execute the function linked to the interrupt matched with the button:.

The potentiometer connected to analog pin 0 is used to choose the sample rate and the period of the singal is given by the sample rate multiplied for the number of the samples. The sketch is composed of two files.

One has the two-dimensional arrays, with the table of the samples for all the waveforms for legibility. Download the attached file, or if you want to start from scratch you have to create a new folder inside your sketchbook folder and place the two files inside.

The sketch file must have the same name of the folder, and the file with the sample table must be named "Waveforms.

I recognized the difficulty a lot of people have with programming the LED cube after building it, so I have made a windows application to make this an easy task. The application will work for those that used an Arduino to control their LED cube. I did not write the LED cube code and the person I got it from didn't either, so I don't know who wrote it, but thanks! I will explain how I wired the cube and how the program works in the next steps. Did you use this instructable in your classroom?

Add a Teacher Note to share how you incorporated it into your lesson. You can download the application and some example patterns from my website mariusck. It was previously available on dropbox, but I have recently moved it here.

It will eventually be available on GitHub as well. The application is made for Windows. If you want to use it on Mac or Linux you can run a virtual OS, I unfortunately will not be developing it for cross-platform.

How you wired your Arduino to the cube is of course very important for this to work. There is a description of the pins in the Arduino code, but I will also explain this in the next step. There are 4 squares with checkboxes. These squares are called plane 1, 2, 3 and 4. The planes represents the cube like you would have seen it if you looked straight at it from the front, so these are the four vertical planes of the cube.

This is so it is easier to visualize your patterns when you make them. If you did not understand the planes you can take a look at the pictures, I will post one there to clear it up. To make a pattern you would simply check the boxes representing the LED's you want to light up and you hit the "Generate" button.

Now you will see a line of code being published in the textbox below. So one generate would make the LED's light up for that certain amount of time, and to make a pattern just repeat this process.

There are some black boxes beside the checkboxes, these are for marking the full line of LED's to save time not having to click every single checkbox. Insert your generated code into this code where it says " Replace this with generated code " and click " Copy to Clipboard ". Nothing else was done so the previous version is just as good, but with different labels of the planes.

Here you will find some fun patterns and one extensive one that you can just open and run right away on your LED cube. This is not a instructable on how to build your LED cube, but I will explain how I did it and how this way is really simple. There are 3 pictures above that shows the soldering of the cube and how to wire everything up to the Arduino.

Hopefully the Arduino drawing will be helpful. This is exactly enough to wire up the cube directly from the Arduino, which was the reason I did it. Because this is only my prototype before making the 8x8x8 cube, I wanted to make it as simple as possible. The Arduino's digital pins can output 5V and 20mA. The 4x4x4 cube is a total of 64 LEDs. The way it's wired it needs 16 digital outs for the Anodes and 4 digital outs for the Cathodes.Pages: [1] 2 3. NeoPixel Code Generator. Once you have to program the Arduino, it begins to be more complicated if you don't find the code ready to use.

So I begun to write a simple led strip effect generatorwhere you can set how many strips you want and give an effect for each strip. It is still in development, but if this can help someone, I can put it on github so everyone can create new effects.

I am still trying to see if it could be something helpful or not. Re: NeoPixel Code Generator. Well done job! Github would be nice as other people can co-develop it.

Nice, just used it for my clock. Save a bunch of time from having to code it myself. I think it is a great tool! Thank you for the feedbacks. Bonjour, c'est un super boulot, pensez vous qu'il serais possible de rajouter des fonctions? Hello, this is a great job, do you think it would be possible to add functions? Ex: button, accelerometer etc? Interaction on neopixel to modify the effects in real time and not just by the loops of the program?

Yes it would be possible. But not in this page. Maybe on a fork or on another page since this was wrote to loop. I wrote it thinking at that. So you have only 1 function in your loop. If you add some sensors or buttons, you can easely add a switch to your loop and execute the wanted loop depending on the button or sensor you activate. But would not be difficult to integrate it on this project.

LED Strip Effects Generator

The problem appears to be because the mathematic equation you're passing those parameters to, does not always produce a whole number integerbut the NeoPixel library is expecting an integer - it does not know how to address LED number I think the solution is to simply round up the numbers to integer values before using them as parameters to call the NeoPixel library.

You can do this by either rounding up the variable after it is output from the equation: Code: [Select]. Code: [Select]. This is a great tool, very usefull, is it possible to be able to select individual LED's so they can be assigned individual effects?

I am making a Nanoleaf clone and want to be able to configure diferent panels different effects. Is there anyway you can explain this coding? I'm trying to do research to understand how to code neopixels and don't want to just copy and paste. Want to understand what I'm trying to code. What do you mean with coding?

How to use the library? Hello, very nice tool!!This is a tutorial on how to easier make patterns for your Arduino-controlled LED cube 4x4x4.

The Arduino code is developed by me, and it is my first Arduino code, I have already explained how to generate SPWM using opamps in one of my earlier articles, you could go through it for understanding how it can be created using discrete components and regarding its importance.

Basically, SPWM which stands for sine wave pulse width modulation, is a type of pulse modulation where the pulses are modulated to simulate a sinusoidal waveform, so that the modulation is able to attain properties of a pure sine wave.

LCD Custom Character Generator

To implement a SPWM the pulses are modulated with an initial narrower widths which gradually get broader at the center of the cycle, and finally end being narrower at the end to finish the cycle. To be more precise, the pulses begin with narrowest widths which gradually get broader with each subsequent pulses, and gets broadest at the center pulse, after this, the sequence continues on but with an opposite modulation, that is the pulses now gradually begin getting narrower until the cycle finishes.

This constitutes one SPWM cycle, and this repeats throughout at a particular rate as determined by the application frequency usually 50Hz or 60Hz. The above explained SPWM can be easily implemented using a few discrete parts, and also using Arduino which will probably enable you to get more accuracy with the waveform periods.

If you have any circuit related query, you may interact through comments, I'll be most happy to help! Your email:. I really appreciate this post. But I have a question regarding soft-start functionality. Please i will be very glad if this can be included with the code. Thank you. I think you can take this issue to Arduino.

Hi Mr. Swagatam, is that posibble to apply your code for 3 phase SPWM with small changes? I mean, by adding new pwm pins to the code, like pin 11, pin 6, pin 5, and pin 3. Is that possible? Hi Fitrah, If you generate them with proper degrees separation then it will work, however I am not sure exactly which Arduino board would be able to implement this.

Thanks for your reply, Mr. So about the degrees phase shift, an article mentioned that to get degrees phase shift, the second signal must start 6. So, should i put some delay into the code? Or could you show me the better way?Morse code is a system of communication to encode any character in two different durations of signals called Dots and Dashes.

Morse code is developed by Samuel F. It was most used at the time of World War II. A Morse code can be performed by tapping, flashing light or writing. The Morse code is available in two versions, the original and the international morse code. In the international morse code, the original version is modified by removing spaces and designing the dashes in a specific length.

The Morse code is available for encoding alphabets and numbers. It is mainly used in the radio and ocean communication and also a part of training for soldiers. Today in this tutorial we will build a Morse Code Translator using Arduino which will take any character as an input from serial monitor and convert it into Morse code equivalent beeps by buzzer.

Upload the code using Arduino IDE and type the characters on the serial monitor to create the sound. A LCD can also be added with Arduino to display the dash and dots. The complete code for Arduino Morse Code Generator is given at the end, here we are explaining the program to understand the working of the project.

The below code is used to receive the character string and then convert it into morse code. Then define the pin for the buzzer connected to the Arduino and the pitch for the sound generated by that buzzer. Then we are defining the length of dot and dash. In the void loop function, if serial data is available, it will save into a variable indata. Then it reads the character one by one using command inData[index1]. The command variable. Then it creates sound according to every character. Below functions MorseDot and MorseDash are used to create the sound for dot and dash respectively.

The GetChar function have the code for all the alphabets. So, whenever we type any alphabet, the respective morse code is taken from this function to create the particular sound.

Now upload the code into Arduino using Arduino IDE and type any character into the serial monitor and hit the enter button to send the characters to the Arduino.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Rename the directory to QRCode if downloaded from GitHub, the filename may be qrcode-master; library names may not contain the hyphen, so it must be renamed.

The following example prints a QR code to the Serial Monitor it likely will not be scannable, but is just for demonstration purposes.

A QR code is composed of many little squares, called moduleswhich represent encoded data, with additional error correction allowing partially damaged QR codes to still be read. The version of a QR code is a number between 1 and 40 inclusivewhich indicates the size of the QR code. Higher levels of error correction sacrifice data capacity, but allow a larger portion of the QR code to be damaged or unreadable. The mode of a QR code is determined by the data being encoded.

Each mode is encoded internally using a compact representation, so lower modes can contain more data. Skip to content.
