* This sketch shows you how to drive a 12V LED strip using a TIP122 Darlington transistor. * The sketch makes the strip LEDs to fade on and off using Pulse Width Modulation. * Use any PWM-capable pin ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

This is the firmware for my desklap. I just moved into a cubicle at the office and we like having the overhead lights off. I would like some task lighting though. I decided to tie together some of the ...

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

Having kids now I thought its time to dust off the old model train set - nothing fancy just plain old 12V DC model. Having kids now I thought its time to dust off the old model train set - nothing ...
