Not sure how to wire my 5VDC to 120VAC arduino relay board



I have a board with 8 relays on it that will take 5v from my arduino and the relays will flip on my 120VAC devices.


I'm not an electrical engineer by any means so I am wondering how to wire my 120V devices into the relays, and how to wire the 5v coming from the arduino to the board.


This is a picture of the whole board, and I wrote the pins names below the pins:

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
