But it could also create analog signals such as a sine wave, sawtooth, triangle or square signals, so it could be just like a small function generator but as we will see later it has its limitations. So, this works with i2c communication. So we connect the SCL and SDA pins for clock...
Support switch the output waveform: sine wave, square wave, triangle wave, etc. Widely application on mcu debugging, car repair, home appliance repair, DIY electronic competition, power-supply debugging, inverter, etc. You can have a try.Features:Resolution: Equipped with 320*240 resolution color...
Waveform generators (also called function generators) are useful for testing and debugging circuits. I often use them to test the frequency response of electronics components like op amp and sensors. This waveform generator is powered by an Arduino. It outputs four waveshapes: sine, triangle, puls...
Arduino Sine wave Generator using the direct digital synthesis Method. Here we describe how to generate sine waves with an Arduino board in a very accurate way. Almost no additional hardware is required. The frequency range reaches form zero to 16 KHz with a resolution of a millionth part of...
The AD9833 can gererate sine, triangle and square waves from 0.1 MHz to 12.5 MHz - the software in this project is limited to 1Hz to 100kHz. It can be used as a sweep generator. Sweep generators help test the frequency response of filters, amplifiers and so on. ...
