My Arduino RGB controller is now even better

I had a lot of fun turning an Arduino board into an RGB controller. If I don’t count building a PC and a few guided projects from the Arduino project book, this was my first real hardware project in years. The controller does what it’s supposed to – it changes the LED colors in my PC based on the current hardware usage: higher RAM usage means more blue, higher CPU usage means more green, and higher GPU usage means more red. There is also an ambient white light when the PC is turned off. All of this is quite a success, if you ask me. But as a tinkerer, I am never fully satisfied. There are always opportunities for improvement. So, for version 2, I focused on the following changes: Reduce the intensity of the ambient white light when the PC is turned off. It’s annoying at night. Control the maximum intensity of the LEDs when the PC is turned on for the same reason. Make the transition between colors smoother. It just looks nicer. Ambient light Solving this issue looked tricky at first:…
