Hi friends, In this post I'm going to control some common anode RGB LEDs by addressing them individually without using any multiplexer IC or something like that.
Hi all, Have you ever heard about a thing that change your dreams to working stuffs? That is Arduino. Arduino is a platform that user can do a fast prototype of his electronic project or new invention and convert that basic idea to a working project. That is the wonder of Arduino.
In this project i'm going to show you how to control the speed of small turbo cooling fan using arduino. Also I have created 5 LED array to indicate the speed level of the fan. Two push buttons are used here to speed up/down the fan.
