I have a lot of components on my breadboard .. and a RGB-LED :)
sometimes.. when I turn a potentiometer.. press a switch.. or just accidently touch the jumper-wires.. the LED dithers..
- is it just because the jumper-wires in the breadboard fit a little lose?
- or is that, because I feed my whole circiut with 3.3V ?? (I mean there are lots of 4051s, potentiometers, buttons, etc.)
- I will need even more components.. should I use a external power supply?
