41 Arduino IO Functions How to Use digital Read & digital Write

Описание: 📘 *Arduino IO Functions | How to Use digitalRead() & digitalWrite() | Arduino Tutorial #41*

In this lesson, we dive deep into *Arduino Input and Output (IO) functions**, focusing on the two most important digital functions: **digitalRead()* and **digitalWrite()**. These functions are the foundation of Arduino programming and are used in almost every project.

This video explains how Arduino communicates with the outside world by *reading digital signals* from input devices like push buttons and sensors, and *sending digital signals* to output devices such as LEDs, relays, and buzzers.

🔹 *Topics covered in this video:*
✔ Understanding Arduino digital pins
✔ Configuring pins using `pinMode()`
✔ INPUT, OUTPUT, and INPUT_PULLUP modes
✔ How *digitalRead()* reads HIGH and LOW values
✔ How *digitalWrite()* controls digital output pins
✔ LED control using digitalWrite()
✔ Button input using digitalRead()
✔ Practical wiring examples and code explanation
✔ Common errors and troubleshooting tips

🧠 This tutorial is designed for:
Arduino beginners
Engineering and diploma students
Electronics and IoT learners
Anyone interested in embedded systems

🛠 *Required components:*
Arduino board (Uno / Nano / Mega)
LED
Push button
Resistors
Breadboard and jumper wires

📌 By the end of this video, you’ll be able to confidently use digital input and output functions in your own Arduino projects.
