I made this Arduino 8 bit binary led counter as a solution for one member from Arduino ... the schematic as usual and in the second one is how the schematic looks on the Fritzing breadboard layout.

[Allan Schwartz] decided to document his experience using Fritzing to design, fabricate, and test a custom Arduino shield PCB, and his step-by-step documentation makes the workflow very clear.

8×8 LED Matrix modules are now widely available, and fortunately they are easy to use with our favorite Arduino microcontroller. 8×8 LED Matrix module have many applications in real life, such as ...

To the human eye, it looks like multiple LED’s are lit up simultaneously. [Alex] planned to use an Arduino to control this display, but it doesn’t have enough outputs on its own to control all ...
