Step 6: LED test
Now, whichever button you press should light up the corresponding LED.
If an LED is constantly lit then you have a bad permanent connection. Try to see if you can see where two layers of conductive fabric might be touching?
If your LEDs don't light up at all:
- Make sure the battery is strong enough to power them all (touch LED directly to battery)
- Make sure your LEDs are oriented the right way (plus to plus, minus to minus)
- Did you forget to make holes in the foam?
