LarsBergqvist / door_open_detector.ino

Created July 25, 2016 08:12

Digispark USB board sketch for sending an 433MHz RF signal when a door is opened

	// A sketch for a DigiSpark USB device that detects when a door is opened
	// The door should have a reed switch with NC (normally closed) connected to the Vin wire of the device
	// When the door is opened, the reed switch is closed and the device is started
	// A 32-nit message is then sent via a 433 MHz signal that can be picked up by an appropriate receiver
	// (a Raspberry Pi in my case).
	// When the door is closed, the reed switch is opened and the device is shut down
	//
	// Depends on the RCSwitch library https://github.com/sui77/rc-switch
	// and the eeprom-library
	//
