Here’s a sneak peek at the new creation. Those small (4 inch dia.) ones are created as teaser/samples of my other, larger objects.
Each has 144 white LEDs. 8 channel PWM to create smooth motion of lights. This microcontroller (PIC16F616) only has one 10 bit PWM module, however I’m combining the hardware PWM with software PWM to create very smooth (equivalent to 16 bit or more resolution) gradation.
