from watching your YouTube videos, I think I know what's causing the problems in your circuit: You are using a 3.3 V regulator, but you have to add capacitors before and after the regulator to give it something to work with. Typically you would add 1 uF from the regulator input to ground and 1 uF from the regulator output to ground. Look into the regulators datasheet. It will contain some application circuit showing these caps.
Have fun,
Markus
Thanks Markus. I will order some.
