Connect the components as per the circuit connections mentioned above. Upload the provided Arduino sketch to the Arduino Uno using the Arduino IDE. Once uploaded, the LED connected to pin 7 of the ...

How it works 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).

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 ...

In this article I will add some simple Arduino LED projects starting with basic ones like how to turn on an LED, blinking, and more. Every step will have the code, the schematic, photos of the project ...
