This is tutorial number 1 from our series of Arduino tutorials and in this part I will talk about blinking an LED using the one already available on the Arduino Uno board or using an external LED to ...

These addressable LEDs can be easily controlled by an Arduino. So, in this Arduino inerfacing tutorial series, we are going to look at how to interface such LEDs with Arduino. We will be interfacing ...

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 ...

The code for the Arduino contains a loop that continuosly runs. The code sets the mouth LED pin to HIGH (The LEDs will turn on). Then the code sets the eye LEDs to high (Turns them on). Then there ...

This project shows how control the brightness of a red LED using an Arduino Uno board. int ledPin = 13; // Define the pin where the LED is connected void setup() { pinMode(ledPin, OUTPUT); // ...

It is a pretty common first project to use an Arduino (or similar) to blink an LED. Which, of course, brings taunts of: you could have used a 555! You can, of course, also use any sort of oscillato… ...

Here is ‘blink’ modified to work TXLED and RXLED as well as LED-BUILTIN. int RXLED = 17; // The RX LED has a defined Arduino pin int TXLED = 30; // The TX LED has a defined Arduino pin // the setup ...
