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 ...

This is just a fun Arduino project that uses leds connected in circle as a ring to produce a rotation effect. You can adjust the spinning speed with a potentiometer and you can also set a minimum and ...

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 ...

In the last installment of The GeekDad Arduino Guide, I introduced you to the Arduino hardware and why it is so cool. Now, let’s start actually using an Arduino. How do you get started? Well, first ...

While regular Hackaday readers already know how to blink a LED with a microcontroller and have moved onto slightly more challenging projects such as solving the Navier-Stokes equations in 6502 ...

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 ...
