This project demonstrates how to connect and control an external LED using an Arduino Uno. It’s a simple and fundamental project that introduces the basics of digital output. In this project, an ...

This is a random oscillogram from D5 of Arduino Uno. During experiments, I powered my Arduino setup with a Li-ion 9V/600mAh USB battery. Quick note: Arduino UNO has three timers – D5-D6 on Timer 0 ...

The setup() function is called once at the beginning to set the LED pin as an output. The loop() function contains the main logic and is executed repeatedly. Usage: Connect the positive leg (longer ...

In this project we are going to interface RGB (Red Green Blue) LED with Arduino Uno.A typical RGB LED is shown in below figure: The RGB LED will have four pins as shown in figure. PIN1: Color 1 ...

For connecting 5 RGB LEDs to Arduino we need 5x4= 20 PINS usually, by we are going to reduce this PIN usage to 8 by connecting RGB LEDs in parallel and by using a technique called multiplexing.

I made this Arduino 8 bit binary led counter as a solution for one member from Arduino forum. He asked if somebody can make a project that displays a decimal number in 8 bit binary format using 8 leds ...

[Dave]’s been working pretty hard on his Arduino driven, LED-lit, magical staff for the past few months, and now it’s finally coming together. He’s using 6 LED strips that contain 55 LEDs ...

When you read “Arduino wristwatch”, you fall into the trap of envisioning an Arduino UNO clumsily strapped to someone’s wrist. [Marijo Blažević’s] creation is much more poli… ...
