==== OpenSprinkler AVR/RPI/BBB Firmware ====
============================================

This is a unified OpenSprinkler firmware for Arduino, and Linux-based OpenSprinklers such as OpenSprinkler Pi.

For OS (Arduino-based OpenSprinkler) 2.x:

--------------------------------------------
Used a Wemos D1 Mini Pro, similar boards should also work. Relays are controlled directly by GPIO pins. The pins are
set to HIGH when the station is active.

Relay pins:
GPIO6  - D0
GPIO14 - D5
GPIO12 - D6
GPIO13 - D7
GPIO15 - D8
GPIO0  - D3

Sensor1:
GPIO3  - RX
