So I've built a buffer using:
- 3.3V power supply module
- 1 Yellow LED(left)
- 1 White LED(right)
- 2 220 Ohm resistors
- 1 1k Ohm resistor
- 1 2N3904 NPN transistor
- 1 jerry-rigged button (push to close)
But for some reason, I can't understand the white LED won't turn on when the transistor turns on.
Leave a comment here or on my youtube video on why I am wrong in my thinking lol.
thanks,
