#169 RGBLedModule

Demo an RGB LED module

Here’s a quick video of the module in action:

RGBLedModule Demo


The RGB LED module is a convenience since it builds-in 150Ω current-limiting resistors for the reg, green and blue anodes of a standard 5mm round RGB LED.


The demonstration program uses PWM to run a series of effects on the module.

NB: on my module, the red and blue pins are incorrectly labeled (swapped around).

This page is a web-friendly rendering of my project notes shared in the LEAP GitHub repository.

LEAP is just my personal collection of projects. Two main themes have emerged in recent years, sometimes combined:

  • electronics - usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting
  • scale modelling - I caught the bug after deciding to build a Harrier during covid to demonstrate an electronic jet engine simulation. Let the fun begin..
To be honest, I haven't quite figured out if these two interests belong in the same GitHub repo or not. But for now - they are all here!

Projects are often inspired by things found wild on the net, or ideas from the many great electronics and scale modelling podcasts and YouTube channels. Feel free to borrow liberally, and if you spot any issues do let me know (or send a PR!). See the individual projects for credits where due.
