“Based on Arduino, it performs electronic light games by piloting a LED matrix thanks to a special multiplexing mode. In the fast paced world we live, moments when we can do whatever we want are rare and we have to …
“This project can be classified as an AAC (Alternative and Augmentative Communication) device, which are used as a means of communication for those suffering from debilitating diseases like ALS and the like, that result in complete paralysis and near-total loss …
“This Instructable shows how to wire a 9-Charlieplexor. (Formally this is a “Charlieplexing circuit with 9 nodes” capable of controlling 72 LEDs or less.) A general method could be taken from this layout for larger Charlieplexors. I will likely put …
Today’s circuit aims to control quite a few LEDs with few pins and without using other integrated chips. The technique used is called charlieplexing and was proposed in 1994 by Charlie Allen of Maxim, having nevertheless been the subject …
