This project demonstrates a simple Arduino circuit that makes an LED blink on and off. The circuit uses an Arduino UNO, an LED, a resistor, and connecting wires. Connect the longer leg (anode) of the ...

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 ...

🎯 What to Try Next? 🔹 Change the delay(1000); to delay(500); to make the LED blink faster. 🔹 Use a button to turn the LED ON/OFF instead of automatic blinking. 🔹 Use PWM (analogWrite()) to control ...

In the last installment of The GeekDad Arduino Guide, I introduced you to the Arduino hardware and why it is so cool. Now, let’s start actually using an Arduino. How do you get started? Well, first ...
