/*
* The MySensors Arduino library handles the wireless radio link and protocol
* between your home built sensors/actuators and HA controller of choice.
* The sensors forms a self healing radio network with optional repeaters. Each
* repeater and gateway builds a routing tables in EEPROM which keeps track of the
* network topology allowing messages to be routed to nodes.

На LM393 установлен простой фото-резистор датчик освещенности, который имеет как аналоговые, так и цифровые выходы. Цифровой выход имеет настройку потенциометром, который используется чтобы установить триггер уровня освещенности.
