I’ve built the circuit and when i push the switch it does not work. PLEASE HELP
Hi Andrea,
We’ll need some more information to help get you on the right track. Could you provide some pictures of your setup showing clearly the connections and components used, including how you’ve got it connected up to the Arduino.
Everything looks ok to me, although I can’t tell if that LED is placed in the correct direction. There is a flat edge on one side which is the negative side, you need to make sure that the lead on the side with the negative edge is connected to Ground (the blue rail).
Thank you so much! It helped
Not a problem, glad we could get you on track.
