How-to Tuesday: Hacking a MAKE gift subscription card

This week I am going to show you how to hack a MAKE gift subscription card. Actually, it’s showing you how to interface a 7-segment display with an Arduino. I just happened to make it into a gift card subscription.

My idea was to give a MAKE subscription to a friend. Actually, I am giving them an Arduino along with the subscription. What a great combination! As a final part of the gift, I am making a post on how to program the 7-segment display to help them get started.
