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.
