WebMay 6, 2024 · For normal charlieplexing, the duty cycle is 1/n where n is the number of LEDs, assuming all LEDs need to be independently controllable. You can only light one LED at a time so you are never going to have to worry about exceeding the Arduinio's capacity to source or sink current. However, good luck with a 1/380 duty cycle. WebMay 6, 2024 · For 6 leds, you only require 3 outputs. Your green leds should be connected between 'ledpinA' and ledpinC For your hardware, make these basic tests on the leds. …

The problem is that I have this reappearing bug that seems to come and go as I place delays in one of my functions. The bug causes my serial input (through the Arduino USB cable) to mess up if I place some delays in a, more or less, unrelated function.
WebFeb 9, 2024 · Charlieplexing. Aside from being a fancy word it is a technique for driving multiple LEDs with relatively few pins on a microcontroller. It allows you to drive N* (N-1) LEDs with just N pins without requiring any additional hardware, making it a quick, cheap and easy way to add multiple LEDs to your arduino projects.
