I purchased the osepp uno r4 http://osepp.com/products/arduino-compatible-boards/uno-r4-plus/
seed studio relay shield v2 http://osepp.com/products/arduino-compatible-boards/uno-r4-plus/
osepp lcd OSEPP - Multi Colored LED Assortment Set
And this rtc 5PCS DS3231 AT24C32 IIC precision Real time clock module memory module Arduino | eBay
I bought this clock because I figured I just needed it to tell the uno what time it is so the uno could run a loop with timers and if then alarms so when the time hits an alarm it will react by switching a relay...... (sorry its been a while this may not be realistic)
I can cancel the time clock as I just ordered it a while ago however i have the other components...
As for a schematic the relay shield plugs ontop of the uno leaving the expanded pins(unique to the osepp uno r4 I will not be using) and the lcd stacks directly on top of the relay shield.... the relays are powered directly by the uno powersupply. the time clock should stack onto the lcd display however if the pinout is different I will connect with jumpers... or direct solder wires.\
hope this is the info you were requesting
