* 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 ...

Step 5 Go to file and select save option to save the program Step 6 GO to sketch and select verify to compile the program Step 7 If no error, Connect the Arduino board to your computer using a USB ...

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 ...

V-LED This is the VCC pin of the LED. Connect this pin to the 5V pin of the Arduino with a 150Ω Current Limiting Resistor. LED-GND This is the Ground Pin of the LED. Connect this pin to the Ground pin ...
