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 ...

What if you could combine the simplicity of Arduino with the power of a Linux-based processor, all in one compact device? Enter the Arduino Uno Q, a new development board designed to handle everything ...

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 ...

Electronic Specifier is giving visitors to its electronica 2026 booth the chance to win an Arduino UNO Q development board.

You can get a long way just using the matrix library, but there is another library, ArduinoGraphics, that has additional functions that make the LED matrix really useful. However, at the time of ...
