Here is a simple, yet useful circuit of an Arduino 4-digit 7-segment LED display unit. The module used here is a self-contained, compact common-cathode module containing four 7-segment LED numeric ...

The below image show the 4x4x4 LED Cube Arduino Simulation, you can see how each pin on arduino nano is able to control the LEDs on our cube individually. Design and Build of 4×4×4 Led Cube using ...

Here is an Arduino based circuit with three independent pulse width modulated (PWM) channels to fulfil your requirements! Just follow the schematic diagram to complete the construction, and use any ...

Circuit and Working Explanation The circuit connection for RGB LED Arduino interfacing is shown in below figure. Here we have connected Common Anode terminal of RGB LED with the 5v supply of Arduino ...

Arduino powered Pac Man Game with one 74HC595 8 bit Shift Registers to control 1-8 pins of a single color 8x8 LED Matrix. A 5 pin 2 axis joystick is used to control the direction of the player on the ...

Here’s a project that integrates an RFID reader, a servo motor, an LCD, 3 LEDs, and a 2-pin piezo buzzer with Arduino. This setup can be used to create an access control system where the RFID reader ...

The RGB LED module lets you make all sorts of colors with just four pins from the Arduino. Learn how to do it here!

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.

Adding to the ever growing list of Ardunio watches being created a new LED Arduino watch has been created that is powered by a supercapacitor.
