An ongoing project to create a cheap simple power meter for my bicycle auto shifter.

Developed over 4 years and 14,000 miles for enviolo (NuVinci) CVT hubs using reed switches and excepts power data for fully auto shifting.

A system that gives my bike front and tail lights, a turn signal, and a speedometer, all in a clean and simple design.

This is an example problem to illustrate the function of a PID controller. You will learn the basics to control the speed of a DC motor.

I used an Arduino Nano to fix my dishwasher.
