In this second article we will see a practical application of the daisy-chained shift registers. We want to use four 7-Segments LEDs controlled by the Arduino board. As you can imagine, that is ...

In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using this setup as a pan-and-tilt controller for a laser pointer. The following is excerpted from the ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led – the green one on the left in the photo. And it has a pair of yellow leds – called TX ...

Need to quickly toggle or read some logic signals without the hassle of writing a quick program? [Thor_x86], aka [Eric], built an Arduino sketch that does just that — and he threw in the ability to ...

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

A Raspberry Pi Zero Shield that will connect a Zero or Zero W module to a 3.3V or 5V compatible Arduino board, is available from US-based Burgessworld Custom Electronics. The two boards are connected ...
