The term “Charileplexing” is not a familiar one for many electronics hobbyists. Charlieplexing is a technique proposed in early 1995 by Charlie Allen (at Maxim Integrated) for driving a multiplexed ...

Charlieplexing. The verb is an electronics technique apparently named after one Charlie Allen, an engineer at Maxim. It involves minimising the use of I/O pins on a microcontroller to drive a maximum ...

Arduino code used to test a 4-pin, 12-LED charlieplex matrix Currently running on an ATTiny85, but could be used on an Arduino-compatible board so long as the definitions at the top of the source code ...

Arduino本体だけでLEDを駆動する方法となると、このあたりまでとなる。もっと多数のLEDを同時に駆動したいという場合は、Arduinoを複数もってくるとか、より上位のArduino MEGAを使うとか、あるいは外部の回路を使うということになる。 Arduinoを複数というのは ...
