From your very first blinking LED to dazzling multi-color sequences, Arduino makes it easy to bring light to life. With just a board, a few LEDs, and some code, you can experiment with patterns, ...

This is a very simple but useful project, strobe navigation lights for rc airplanes, or you can adjust the flashing time and make it a warning light for a forklift or even a turn signal light for a ...

If you were to point to a single device responsible for much of Hackaday’s early success, it might be the Arduino Uno. The ...

Generally when a game console with an optical drive stops reading discs the first thing that people do is crank on the potentiometer that controls the power to the laser diode to ramp up its output.

This project demonstrates how to control an LED using GPIO in STM32 microcontroller. The STM32 microcontroller continuously turns an LED ON and OFF with a delay of 500 milliseconds. This creates a ...

Measuring the speed of a rotating object is a common requirement. Knowing the speed of table and ceiling fans, as well as kitchen appliances such as mixers and grinders, can often be useful. However, ...
