Reply To: Trying to power illuminated arcade Button (12v)




A 12V bulb, specially a filament light bulbs (old ones), drains too much power from the Pi. I asked my dad about it (he’s an electrical Engineer, duh!), he recommended changing the bulb to something that uses less current, so i changed the bulb to a 3v wide white led, and connected the 3v pin and grnd to supply power, works perfectly.

I hope this thread help’s someone.
