WebFeb 20, 2013 · The chip makes sure all your LEDs are running at optimal power and protects your Arduino from the stress of charlieplexing. Charlieplexing is a great way to control a lot of LEDs, but using LEDs with built in resistors might be an issue, since you will be always using 2 resitors anytime you try to light an LED.

Charlieplexing: Controlling 6 LEDs with 3 Pins CuriousMotor

WebI use an attiny 85 programmed with the arduino sketch. So it uses 5 pins for 20 leds. If you want more: 6 pins for 30 leds, 7 pins for 42 leds, 8 for 56 leds...use an atmega328p/644p/1284p. So each led, one by one (D1 to D20) are switched on and the fade off every four leds to give a rain effect with a random cycle. WebMay 6, 2024 · The Wikipedia article on Charlieplexing says that you CAN turn on more than one LED at a time if they have a Common Anode. Set the common anode pin HIGH and set the two cathode pins LOW. I think the Common Cathode configuration would also work. Set the common cathode pins LOW and set the two anode pins HIGH. WebCharlieplexing (also known as tristate multiplexing, reduced pin-count LED multiplexing, complementary LED drive and crossplexing) is a technique for driving a multiplexed display, keypad or touchscreen , in which relatively few I/O pins on a microcontroller are used e.g. to drive an array of LEDs..

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.
