This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

Spinning poi is an entertaining pastime, and LEDs can make a great addition to the experience. [MilanDer] built some LED poi of their very own, using a few maker staples along the way. A 3D printed… ...

Arduino already include on-chip PWM controllers, making this effectuation easy. In short, PWM is a way of digitally encoding analog signal levels. MyDuino! Looking for a solution to build this circuit ...

In recent episodes, she taught her audience how to build squishy circuits with LEDs and a heartbeat-sensor pendant using LilyPad, an Arduino microcontroller board designed for textiles.
