Weekly Switch Clock – Hardware

I am using:

• SainSmart Mega2560 Board+3.2 TFT LCD Module Display+Shield Kit For Atmel Atmega AVR 16AU ATmega8U2
• A DS3231 Real Time Clock
• A DCF77 Receiver from Pollin
• A 434MHz Transmitter from Watterott
• A PC loudspeaker as a case or whatever case suites you best.
• RC-Switches from Pollin

 Layout and cabling

Please excuse that I do not have a part for the 434Mhz module for the fritzing software. Please have a look at the rc-switch wiki for cabling.

Pleas note that the DS1307 and the DS3231 have the same connectors. Only the library has to be switched.
