Pushbutton test board

[bsnut]

I need a way to test my code for my projects. So, I made this pushbutton tester to plug in the Prop-1 or the HC-8+ (mainly for the HC-8+ TTL input header). But, one cool thing is I can use this to test the ULN's on my Prop-1 on even a Prop-2. But, it's best to load a blank program like "Hello World" on the Prop-1 or 2 first.
