Using intelligent LED pixels spares quite a lot of CPU cycles.

A strange game...

M2 Torx. No traces in the way.

Death to Phillips screws and other stuff that cams out way too easily, ruining the screw in the process.

Just testing if the latest change to the schematic of a project really works. It does.

Unfortunately now I have to patch some libraries as well. Otherwise there is a beat-note in LED brightness due to unsynchronized PWM interaction.

Fortunately I don't HAVE to use the PWM functionality of that pin, but I could...

The AVR controls the brightness of the LEDs using 'BCM'. This gives a 6-bit resolution per color channel.

This printed circuit board was ordered at Seeedstudio and uses traces as narrow as 6mil.

It also works with a slightly modified version of the Arduino ShiftPWM library. That delivers extra-smooth color fading.

Some quality colors

BCM vs. dumb software PWM

Both are interrupt driven. The left side uses BCM (Binary Code Modulation), the right side uses 'dumb' software PWM.

Identical hardware!
