After my previous article on the MAX6969, I’m investigating the reason of the strange visual artifacts on LEDs when changing data.
Today I decided to take the MAX6969 sample a step further using Pulse Width Modulation (PWM) to vary LEDs intensity.
I recently ordered a bunch of sample MAX6969 from MAXIM. These are 16 ports current LED drivers I’m planning to use to drive optoisolators (MOC3041). In my first attempt, I used an Arduino plus a bunch of LED and made them blink of course.
