In the previous chapter, we stored the current state in a variable and switched the LED operation mode every time the button was pressed.The signals sent to the LED so far have been of two types: HIGH ...

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 ...

In the previous chapter, we used a light sensor to read the ambient brightness as a value from 0 to 1023.This time, we will ...

Here is an artistic Arduino project for the fun-minded. The circuit is an Arduino RGB LED controller running on a sweet ‘n’ simple code,but with a little hardware surprise outside the Arduino board.

If you searching for an LED matrix for your next project or to add to an existing application you may be interested to know that the Maker LED Display is now available to purchase from the Crowd ...

There was a time when building electronics and building software were two distinct activities. These days, almost any significant electronic project will use a CPU somewhere, or — at least — could.

Light-emitting diodes (LEDs) are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the ...
