ESP8266 Gate Opener
This sketch is for a simple ESP8266 WiFi Web Server that listens for requests to /gate/press
and triggers a relay for 750ms. The ESP8266 is a low-cost Wi-Fi microchip, with a full TCP/IP stack and microcontroller capability. This means it's an ideal microchip for IoT Devices.

Components Used
- LOLIN D1 mini - The ESP8266 Board
- D1 mini Relay Shield - The Relay shield for the D1 Mini
- A spare Garage Gate Remote Controller
How it works
The way this works is by taking a spare Garage Remote Controller (that works) and unsoldering the push button that opens the garage gate and instead soldering two wires; a red one from the +
side of the circuit and the a black one on the -
common side:
Connect the Relay Shield to the D1 mini and connect the Red +
wire to the NO
(Normally Open) pin and the black -
wire to the COM
(Common) pin.
