This is a newbie on using the GPIO on the Raspberry Pi. I also did some search and reading about using the GPIO, but I am confused
What I'm going to do is to attach an 8 relay to the RPI.
There is a link on the site for more info but it only relates to the relay.
I went for this relay after seeing this video on youtube .
Do I need some sort of buffer in-between the RPI and the relay board or can I use pin 2 and 6 on a Raspberry pi V2 to power the relay board or both?
