Here's a simple two LEDs example: You can easily see that each LED is set on and off by setting one pin high and the other low - the … WebAug 6, 2024 · We previously used multiplexing technique in Arduino to interface 4-digit 7-segment display and driving 8x8 LED matrix. Charlieplexing allows you to control N * (N – 1) LEDs, where N is the no … Charlieplexing (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. … See more The Charlieplexing technique was introduced by Maxim Integrated in 2001 as a reduced pin-count LED multiplexing scheme in their MAX6951 LED display driver. The name "Charlieplexing", however, first … See more Refresh rate Because only a single set of LEDs, all having a common anode or cathode, can be lit simultaneously without turning on unintended LEDs, Charlieplexing requires frequent output changes, through a method known as See more In the following Arduino code example, the circuit uses ATtiny 8-pin microcontroller which has 5 I/O pins to create a 7-segment display. Since a 7-segment display only requires control of 7 individual LEDs, we use 4 of the ATtiny I/O pins as charlieplexed … See more • Gadre, Dhananjay V. (2007-01-18).
