I'm making a chess set for class, and I wanted mine to glow with LEDs. I wanted to have a LED in each piece and when it was placed on the board it would light up. I don't know about this electrical stuff but I learn quick. I found some tutorials online, but look a bit complicated. They use an AC power supply, but I was thinking maybe I could power it with small watch batteries. If I placed a battery on each square of the chess set, would that be sufficient power to light one LED up?
