A large installed base of powered speakers from a defunct manufacturer and a dwindling supply of working remote controls. Sounds like nightmare fuel for an AV professional – unless you take matters ...

I made this Arduino project that allows to turn ON and OFF LEDs using a cheap IR remote control as a preparation for the next big step: disassemble my girlfriend’s chinese LED lamp and replace its ...

An Arduino-based project to control an LED wirelessly via Bluetooth using the HC-06 module and a mobile app. Firmware for an interactive LED map of the Czech Republic, based on ESP32 and AWS IoT.

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 ...

An interactive AI-powered robotics project that translates real-time human hand gestures into hardware control signals. This system uses a computer vision pipeline developed in Python to detect hand ...

In this step-by-step tutorial, we're diving into the world of electronics and microcontrollers to create a personalized 8 by 8 LED matrix that can be controlled using an Arduino board In this ...

At Hive13, a Cincinnati-based hackerspace, they like to hack everything – even their bathroom. One of the bathroom’s walls faces the street, and is made up of thick glass privacy blocks. A few years ...

Here is a 3D light show that will astound you with its combinations. Inexpensive and easy to make thanks to an Arduino controller, the design enables you to play with the existing effects and, most ...

The 8x13 blue LED matrix is also an example of using PWM to implement gray-level images. The LEDs are connected in a row/column layout in the form of a tree – the first row has one LED pair, the ...
