Arduino programs that allows manipulation of the Si5351 to produce a poor man's Sig Gen. Its a work in progress and there are a few improvements and a few bugs to be fixed. Caveat emptor. My original ...

This simple signal generator will produce a 1kHz square wave when the Arduino is powered up. If you connect to it using a serial monitor (PuTTy or the serial monitor in the Arduino IDE) at 115200 baud ...

Anyone searching for a function generator may be interested in a new DIY Arduino project which details how you can make your very own. “A function generator is a very useful tool, especially ...

The Arduino Mega2560 is based around the ATmega2560 8-bit, 16-MHz microcontroller. It has a total of 54 general-purpose input/output (GPIO) pins configured into six 8-bit and one 6-bit ports.

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 ...

Versatile low-cost audio signal generator and pulse generator (up to 4MHz) based on Arduino Nano MCU module. Waveform generators, also known as “function generators”, have been popular DIY projects ...

ERAsynth is an open source, crowd-funded project — now available on Crowd Supply — aiming to make multi-GHz RF signal synthesis accessible to everyone.

[Leigh] is a HAM operator (you may know him as wa5znu). He is familiar with a signal visualization tool called a waterfall which plots signal strength and frequency over time. He wanted to build hi… ...

I am not sure why pulse generator buffers are so fascinating at the moment. 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 ...
