Arduino Timer Relay with RTC & LCD Keypad Shield

Описание

I build a timer relay based on Arduino Uno microcontroller. It will switch on and off devices on configured time. Relay configuration is accessed from LCD keypad.

I put a DS1302 RTC module on a proto shield, and sandwiched it between Arduino and LCD Keypad Shield. I use 4 Relay Module because I didn't have 8 Relay Module available, but the system is ready to accept up to 8 relays.
