Layman’s RGB LED module is an ultra-simple project realized without any microcontrollers. An RGB LED can be driven with a cmos presettable up/down counter. This is accomplished by connecting the three ...

This article describes a rainbow flashlight I designed for a personal project. The intended application compels a multimode, multicolor, compact flashlight/tent light to be driven by a small built-in ...

In this code we'll cycle through 13 colors before turning off for a common cathode LED. This will work if you are using a common anode LED strip connected to a transistor. This will not work for a ...

I will use the 5V rail on the RPi, and divide it into one parallel circuit for each LED to connect to the anode. I will run the RPi pins to the ground pins of each LED individually. IMPORTANT: USE THE ...
