RFToy is an Arduino-compatible gadget for interfacing with radio frequency (RF) modules. It can be used as a standalone gadget, or in conjunction with OpenSprinkler (including DC / AC / Pi) to decode and simulate RF signals on RF remote power sockets. This allows OpenSprinkler to switch not only sprinkler valves, but other general devices such as lights, heaters, fans etc.

This is version 3.0 with built-in WiFi support (using ESP8266). The kit includes one fully assembled RFToy, with a pair of 433Mhz transmitter-receiver and a pair of 315Mhz transmitter-receiver. Includes screws and standoffs (does NOT include enclosure).
