[Edward], creator of the Cave Pearl project, an underwater data logger, needed a way to measure temperature with a microcontroller. Normally, this problem is most easily solved by throwing a ...
This project implements a closed-loop temperature control system using an Arduino-based PID controller and TRIAC-based AC power control. The system compares multiple temperature sensors (LM35, RTD, ...
Before I start talking about this really cool thing called Arduino (Italian for "good friend"), let me say a few things about the fascinating subject of physical computing. Physical computing has been ...
