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 ...

Demonstrates periodic LED blinking using **hardware timers** instead of software delays. This allows the Pico to multitask while the LED toggles automatically. A lightweight Arduino library for ...
