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 ...

Is not a complicated project so it can be done easily by anyone who has an Arduino board or an Atmel microcontroller with bootloader on it. I have used red LEDs because at the moment the white and ...

Here is a simple project to control the intensity of three LEDs, one Red, one Green, you can guess the last one is Blue. This is the Arduino part. It controls the arduino LED intensity when the socket ...

// initialize LED Pin as an output.

The circuit is nothing but a portable four-channel, multi-mode digital light controller, realised using very few external components. Four LEDs are made to glow in different sequences and patterns, ...

This flasher has a chip that controls the random flashing rate of the LEDs. The circuit diagram of the LED flasher using Arduino is shown in Fig. 1. The circuit is built around Arduino Nano board ...

Arduino based program development environment is an easy way to write the program when compared to other environment development programs. Here we are going to write a program to blink an LED for ...

Instead of the relative horror of driving 40 LEDs with a single Arduino ... To actually power and control the entire circuit, [Martyn] used an Arduino loaded up with a program based LedControl ...
