LED gravity balance simulates a moving particle

This is a nice project by Roel Arits. The project appeared on www.elektormagazine.com and you can find the source files there. This project has no practical use at all, but was initiated as an exercise in implementing physics formulas related to gravity in C-code on an Arduino. To make...

APP NOTE: Digital potentiometer to control LED brightness

Controlling LED brightness through digital potentiometer and a LED driver from ON Semiconductor. Light-emitting diodes (LEDs) require a regulated current, and their brightness is proportional to the current that flows through them. Some LED drivers use an external resistor to set the...
