Controlling LEDs with A Multiplexer and Arduino — Maker Portal

A demultiplexer will be used to control 8 LEDs using just 3 digital pins on the Arduino board. This method of demultiplexing frees up pins on the Arduino, but also makes control of multiple LEDs easier by consolidating the power given to each LED. This will allow us to use LEDs without resistors.&am

This blog is intended for young innovators interested in real-world applications to engineering. A maker-based approach is explored through written articles using Raspberry Pi and Arduino as central and control components. Topics range from heat transfer, acoustics, robotics, data analysis, sensor design, and more. Difficulty levels range depending on the topic and there is extensive focus on open-source software implementation, however, there will be articles with a focus on software design as well. The intention is to demonstrate applications of engineering that are repeatable at the intermediate level without requiring colossal resources.

I don't get why the LED is still going when port 13 is set to high. If anyone could explain that would be great! :) : r/arduino
