This tutorial shows how to make a simple waveform generator using the Arduino and the DAC features of the Arduino Due board. Waveform generators (also called function generators) are useful for testing and debugging circuits. I often use them to test the frequency response of electronics . An Precession Signal generator is very easy and affordable make using an arduino and dds synthesizer (ad9850). Its World’s first smallest portable signal . Intro: Resistor Arduino Waveform Generator.
If you have an Arduino UNO this project is practically free!
It also makes a great Arduino Nano project. BOB-11420: This is the SparkFun MiniGen Signal Generator, a small shield for the Arduino Pro Mini that is capable of generating sine, square, or triangle waves . Arduino Waveform Generator Shield Kit from Jameco, if. A function generator capable of producing a square wave with varying duty cycle, sin wave, and sawtooth wave. Using a arduino and some resistor to work as a 8bit DAC, so we can make some waveform form it , build a Arduino simple signal generator.
This is my arduino-based waveform generator using a 8-bit resistor ladder DAC. It runs with a sampling rate of 655Hz and can create any .
