hi, I have built the 28 pin version of the IC Tester. may first question is how do you assign pins to ground or VCC. Like the 7476, ground is 13 and VCC is 5. Also if the the VCC for the ZIF connector does not come from the Arduino where does it come from.
I would like the code also, thanks for the great instructable. email@example.com
