a tiny software UART TX for the AVR ATtiny

“The serial port is a very commonly used interface for communicating between a microcontroller and a PC for debugging or sending or receiving some values. Most microcontrollers include a hardware peripheral called UART (Universal Asynchroneous Receiver Transmitter) which handles the …

Angstrom - a Tuneable LED Light Source

“Angstrom is a 12 channel tuneable LED light source that can be built for under 100. It features 12 PWM controlled LED channels spanning 390nm-780nm and offers both the ability to mix multiple channels to a single 6mm fibre-coupled output …

Arduino 3D printed radio controller

“Yes, I’ve made another radio controller. Why? well, I wanted to have a more commercial look. So, I’ve designed a 3D case, then I’ve used some high quality joysticks in order to have better analog read, It …

Arduino Analog Value Plotter

“A while ago, I figured it would be pretty handy to have a graph for my analog outputs. It would help debug my outputs, give me a general idea of the sensor’s limits and whatnot, and would even be …
