Description A versatile signal generator using Arduino and AD9833 module to produce adjustable-frequency sine, square, and triangle waveforms. Features a rotary encoder for frequency adjustment, ...

1. Arduino Board: The heart of the project. An Arduino Uno or similar board will work perfectly. 2. Rotary Encoder: Used for adjusting the frequency and amplitude of the generated signals. 3.

Granted, $200 is not a lot to spend compared to what a lab-grade signal generator with such a wide frequency range would cost. And sure, external filters could help.

This waveform generator is explicitly intended to support signal processing learning. This low-cost waveform generator can produce multi-frequency signals with high sampling precision and linearity ...

It could be that the workshop’s only crystal-backed generator that can run from 0% to 100% duty cycle is still broken, or it could be that it is simply an enjoyable bite-sized problem to ponder at ...
