The controller regulates the fan speed using PWM, and the full PWM range (0 - 100%) fits into the temperature range of 25°C - 40°C. Unlike the ATtiny10-based project, this device can poll up to 8 ...

Almost a month ago I started trying to reverse engineer an inexpensive LED color changing light bulb. With your help I’ve mapped out the circuit, and taken control of the bulb. But there’s still a few ...

Imagine you’re stuck on a desert island, hundreds of miles away from the nearest person, and you finally have time to finish that project you’re working on. You have a single microcontroller, but ...
