This DIY electronics project uses a small vibrating motor to gently wave a tissue paper heart and flash an LED when it receives instructions over the internet from another device. I built two versions of the ESP8266 wifi circuit, also equipped with two buttons for triggering the two commands. The devices talk over the Adafruit IO cloud data service to communicate with each other from anywhere with wifi, and I'll show you how to activate your valentine with the API gateway service IFTTT as well, in case you only want to build one valentine circuit."
