Oh by the way I have just completed my first serious project. It even worked to my amazement.
Knocked up a box that tests trailer lights for a friend. It simply plugs into the truck trailer and runs a short program to switch the lights on in a sequence so he can do a visual check as he walks round the unit. He is a mechanic and works for a supermarket/superstore chain.
Used one of the circuit boards with 8 relays on it. Very pleased with the outcome.
