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 ...

LED candles are neat, but they’re very suboptimal for wish-making: you can’t blow them out. Unless you take the circuit from [Andrea Console]’s latest project that lets you do just that, using only ...

Last time, we used a light sensor to measure ambient brightness and even created a control system that turns on an LED when ...

Maniacal Labs have once again taken to Kickstarter to raise funds to help take the new digital controller which has been specifically designed for analogue LED strips and aptly named the LongPixel ...
