Arduino custom shield isn't working right... Answered
I've been trying to figure out whats wrong on the shield i built for my intervalometer project but somehow nothing is working except bottom row of the screen (standard 16x2) is all lit up. I've checked my wiring, shoddy as it looks, several times over but nothing seems amiss. WTF is wrong?
Then tonight it occurred to me, perhaps its the Vin pin that I neglected to put in since I wasn't going to need it for this project is the cause. Am I close to what might be wrong?
