Keychain-PCB

My first PCB design. Made for solder at hackclub, a challenge that requires the partticipants to build a PCB using limited components. It is a Keychain based on my PFP(profile picture) on hackclub's slack, @GB114.

Features

• Two LEDs that light up when SW1 is pressed.
  • Photoresistor with transistor(NPN) to not turn on the LEDs in bright environments.
• DC_Motor(Vibrator) that vibrates when SW2 is pressed.
  • The intensity is adjustable by a potentiometer.

How to get yours?

• Just take the gerber.zip file from the production folder and give it to your manufacturer. (or manufacture it yourself.)
