Hello, I have a TLC5940 connected to an Arduino runing off 9v mains power and 14 LEDS.
My problem is that the leds will only illuminate when my finger is held near the legs of the LEDs. Pushing down on the TLC5940 also lights them, I suspectded a short circuit on my breadboard, but if they're lighting up with my finger near them, surely not a short? I have built this on three different breadboards, same result every time, also tried swapping chips!
Attached pic shows the circuit.
Any ideas greatly appreciated as this has me tearing my hair out!
