Taking what I've learned about LED color mixing and Python, along with our LumiDrive LED Driver and LuMini LED Ring, I set out to create a light ring for macro photography that surpasses all others.
Last week, we took a look at using the digital pins on our new LumiDrive LED Driver. This week, we'll play with the analog pins, and see if we can't put something together using both!
The serial controlled motor driver is stripped of its firmware and reprogrammed to function as an amplifier. Then it's surrounded with circuits that turn the whole shebang into a portable guitar amp.. but it won't win any awards.
