ESP8266 touchscreen WiFi light controller and clock
Spiros Papadimitriou has build a WiFi light controller and clock based on ESP8266: A couple of months ago I picked up cheap WiFi-controlled LED bulbs (one among dozens of very similar devices), after seeing them at a friend’s place. This turned out to be an excuse to play with the...
