I use pulse width modulation (PWM) techniques to control the brightness of light emitting diodes (LEDs) in many of my microcontroller projects. I can set my LEDs to the exact brightness level I like ...

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 ...

The Arduino can just increment the counter up to the appropriate LED. The Arduino then controls the state of the LED using the active high enable line from the column multiplexer chip.

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 ...

Low-cost thermal camera built using Arduino 7:59 am August 11, 2023 By Julian Horsey In the realm of DIY electronics, the Arduino UNO has emerged as a versatile platform for a myriad of projects.

Description: Using an Arduino or a micro controller we can generate cool looking patterns with an led strip with addressable LEDs. In this case I'm using an Arduino uno (clone board) and a strip of ...
