Note that humans perceive the brightness change non-linearly. The human eye responds to light in a logarithmic fashion and has a better sensitivity at low luminance than high luminance. If you do not ...

Here is a simple Arduino Camping Light project. In this design, only one push button switch is used to control the light output (from a bunch of white LEDs) between off, dim, medium, and full ...

Powered by an Arduino Uno, the light painter provides a user interface on a 16×2 LCD which allows control over not only the brightness of the WS2812 LED strips but selecting and loading different ...

The statement analogWrite (3,i); is how PWM is implemented in the Arduino. Pin 3 will output a square wave with a certain duty cycle. A value of 0 means a duty cycle of 0%, or completely off.

He ended up designing an 8 by 16 grid of LED’s that was turned into a game of Tetris. He arranged all 128 LED’s into the grid on a piece of perfboard.

A case will protect your Arduino and ensure your sweater has the chance to light up the room for many holidays to come.

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 ...
