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 ...

The Arduino then controls the state of the LED using the active high enable line from the column multiplexer chip. [Alex] wanted more than just a static image to show off on his new display, so he ...

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...

Chapter 1, page 11 This code is basic but allows the reader to gain insight into key elements for several other projects in this book. It combines two pieces of code that are listed in the examples ...

Achieving accurate 13-bit color can be achieved with a dual buck LED-driver architecture that has I2C control. It’s able to drive multiple LEDs or strings of LEDs with high current ...

This Instructables guide will show you how you can use an Arduino to control your TV, DVD player, VCR, and countless other home electronics.

Control system upgrades can transform lighting from an operational necessity to a valuable building asset. If the existing lighting system consists of basic switched fluorescents, adding controls as ...

The infrared remote control might not hold the seat of honor in the average home theater setup that it once enjoyed, but it’s not quite out to pasture yet. After all, what are you going to us… ...
