Скачать или смотреть ESP8266 Hacked Projector Controller Becomes WiFi IoT Smart Switch

Here is a little hacked projector controller turned into a WiFi enabled smart switch. I installed an ESP8266 based EPS-01 module, which connects to an MQTT server (via WiFi) and listens for instructions. It controls the relays in this repurposed projector controller. The projector controller had a little radio receiver and custom microcontroller in it, both of which I removed. I added some power regulation circuitry and connected the ESP-01 to a relay driver chip that was in the unit, along with some pullup resistors to force the ESP to boot properly.
The code is based on the example Arduino code for MQTT communication from the Adafruit MQTT library.
