Blue light in the evening can create problems for your sleep. Especially very white LED lights around us produce lots of it and prevent us from falling asleep after a hard days work. Let's build a "Sleep accelerator" device using an ESP8266, an IR LED, and a MOSFET. It reads actual sunrise and sunset times as well as the time and synchronizes the color of your LED with the sun.
