[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly ... up to the motion controller upstream. The Arduino source for this can be found on the project ...

This DIY solar tracker project mimics this behavior using three simple main components: An Arduino UNO board, a servo motor (with a sunflower paper decoration attached), and two photoresistors ...

but getting an Arduino starter kit is more convenient. Most already come complete with the UNO board and a bunch of components like LEDs, a temperature sensor, a DC motor, a servo motor ...

Most of us are familiar with the Arduino Uno, a starting place for electronics projects since 2010. But what if the Arduino Uno was released in 1980? You’d probably get something like ...
