IoT Geocache WiFi
This project is made using the capitive portal Sketch with the Nodemcu esp8266.
The circuit Turns on when the button is held which turns on the relay and broadcast's the wifi signal. The capitive portal when opened in a browser will give the Geocacher the information needed. After 5 miniutes the sketch using the millis() function shuts down the relay which turns off power to the relay and disconects the battery.
