Hi there, am @moonbeeper on slack and this is my first ever pcb made for solder.
It's a quite simple pcb. I've been playing around with falstad to create this starting point.
The board has two LEDs that turn on when it gets dark. There's a button to turn the LEDs on manually, and a potentiometer to adjust the sensitivity. The second button turns on a vibration motor.
