Enthusiast Graham McMicken has designed and built an impressive Arduino-powered home thermostat system that not only looks good, but has a graphical user interface and also infrared remote control. Based on an Arduino Mega, real-time clock IC and various 1-wire temperature sensors, the final result is a winner.
Impressive! This is an excellent example of how you simultaneously build your own replicas of commercial products, learn something and save money.
