About 3? months has passed but today finally my mega arrived! The mail man was on his bike... No idea where he started though
Anyhow, I've got some questions and I was hoping you will give me a quick start by answering them.
1. Do I need to power up both the mega and your extension board? Or does your board supply power to the mega?
2. I can't figure out the pin layout by looking at your code. Can you give me a hand by filling/checking the list?
