Procure one Atmega328 chip with pre-burned Arduino Bootloader Replace the original chip in your Arduino board with this one Now upload the sketch to the 328 chip ,as usual, using Arduino IDE Remove ...

(proof of concept – from author’s lab) More Projects It is possible to drive a number of addressable LEDs using just one microcontroller pin as shown here. So you can build your own LED strips, rings, ...

He calculates that it is possible to control up to 96 of these shift registers, each driving 8 LEDs, with reasonably satisfying results.

Eight-pin microcontrollers offer numerous peripheral features. However, the maximum number of I/O pins available is often limited to six, since two pins would be required for ...

Driving multiple LEDs with one microprocessor GPIO pin is a well-known technique. Here's a way to accomplish the task that's simpler than other methods.
