Overview

Some of the earliest projects I have photos of, from when I was in primary school and around 11 years old.

2016: Bluetooth RGB LED controller

I built a remotely controlled LED-strip controller with an Arduino, a Bluetooth module, and N-channel MOSFETs. I hand-wired the circuit on perfboard and fitted it into a plastic enclosure.

  • Switched the red, green, and blue channels with N-channel MOSFETs
  • Controlled the LED strip remotely over Bluetooth
  • Hand-soldered the perfboard circuit and packaged it in an enclosure
