You can find a LED and an Arduino microcontroller board in almost every maker room, but using these two components, there is no space for too much innovation. A simple project can be transformed into a complex one if several dozens LEDs are linked into geometric designs and controlled via the microcontroller board.
An interesting project was added on Instructable where 64 LEDs were soldered at the corners to form a cube. All of these LEDs are controlled by an Arduino UNO microcontroller and enjoy us with a captivating desktop light show. The price of the materials, including the 64 LEDs, resistors, wires, or power supply is around $15.
The cube is designed with 4 positive layers and 16 negative columns. All of these layers and columns are wired to the Arduino UNO.
The tutorial with steps and with Arduino sketches is available here.
We all enjoy a good Arduino project, and in this tutorial is explained step-by-step how to build a 64 green LEDs cube with Arduino UNO and how to create the special effects.
The classic role of an LED was carried on with special effects in a game of light.
Here is one of the best things that you can do with several dozens of LEDs and an Arduino UNO.
