  • I bought this and hooked it up to a LED but I can’t seem to make it light up. Tried it w/the very tiny lilypad LEDs, too. I’ve tried the same thing w/the round piezo sensor with success, so I know it’s not the bulbs. What am I doing wrong? I’ve tapped, bent, and hummed into the sensor.

No public wish lists :(
