Topic: Controlling lots of LEDs (Read 1 time) previous topic - next topic


I need to control 25 LEDs with my arduino uno individually. If there were 25 different pins then I could just hook up one to each pin, but that is not the case for me. What is the best way to do this?


You should consider using a shift register. Here is a tutorial:


The Gadget Shield: accelerometer, RGB LED, IR transmit/receive, speaker, microphone, light sensor, potentiometer, pushbuttons


.. or the more expensive, but less soldering solution of using an Arduino Mega.

More pins than you can shake a stick at.
