Arduino boards — specifically the Uno — have made prototyping your invention easy and inexpensive. On the other hand, one thing they don’t have is a visual indicator as to which pins are high and low (0 or 1). Naturally, this would be excellent for troubleshooting, so Bill Brown has come a solution as DeDe, or the “DEbug & DEvelopment” shield for the Arduino Uno and compatibles.
