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 ...

To build your own function generator, you will need a few essential components and tools. The project is designed to be accessible even for those who are relatively new to electronics and Arduino.

Connect + (plus) and - (minus) rows on the breadboard to the 5V and GND pins on the arduino board The trimmer controls the LCD intensity Take a look at any existing issues on this repository for ...

Arduino PWM. As you may know, two PWM outputs of Arduino Uno are linked to the timers. For the “common” PWM, if we write a value from 0 to 255 on a PWM pin, the Arduino library will drive the assigned ...

[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… ...

Remarkably, the ERASynth from ERA Instruments uses a multi-loop PLL architecture to provide continuous frequency coverage from 250 kHz to 15 GHz in 1 Hz steps. That’s in contrast with single-loop ...

This research aims to create an arbitrary waveform generated by simulation to be observed using an oscilloscope. This waveform generator is explicitly intended to support signal processing learning.

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 ...
