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 ...

Control three LEDs using three push buttons with an Arduino Uno. This project demonstrates how to control three LEDs using three push buttons with an Arduino Uno. Each button controls one LED, ...

You can control the brightness of these LEDs using variable resistors VR1, VR2 and VR3 respectively. Parts Needed. Arduino UNO board – 1 ; 5mm LEDs Red, Green, Blue – each 1 ; 100K Variable resistor – ...

First, upload the following PWM sketch to your Arduino Uno r3/Nano v3 and connect a 10mm water-clear green LED to D9. const int ledPin = 9; // Test LED wire to D9 void setup() { // Set the pin as a ...

Controlling LED Brightness using Arduino and Node.js Webserver. Similar to Blinking an LED with Node.js, this section will also have some parts i.e. Setting up Arduino UNO, Setting up Web Interface ...

Using an IRFZ44N, I made a simple LED driver and used an Arduino Uno directly. Remember the Arduino pins go up to 5V and I used the fade example that generates PWM out of the box.

ARDUINO UNO is an ATMEGA controller based board designed for electronic engineers and hobbyists. Arduino based program development environment is an easy way to write the program when compared to ...
