Arduino Programming Basics for Beginners | ESP32 Tutorial | Full-Stack IoT Bootcamp Ep.7

Welcome to Episode 7 of the Full-Stack IoT Bootcamp! Today, we’re diving into Arduino Programming Basics specifically for the ESP32 using the Arduino IDE. Even though we are programming the ESP32, we use C/C++ with Arduino-specific functions. In this tutorial, you'll learn the core concepts every embedded engineer needs: how the void setup() and void loop() functions work, how to use digital pins as outputs to blink an LED, and how to use the Serial Monitor for debugging and sending commands to your board. ⚠️ Important ESP32 Tip: We also use a multimeter to demonstrate that the ESP32 operates on 3.3V logic, unlike older 5V Arduino boards (like the UNO). This is crucial when connecting sensors! ⚡ WHAT YOU WILL LEARN: ✅ setup() vs loop() — the heartbeat of every Arduino program ✅ digitalWrite() & digitalRead() — control LEDs and read buttons ✅ Variables & data types — int, bool, float, unsigned long ✅ if / else if / else — making decisions with your hardware ✅ for & while loops — repeat actions with full control ✅ delay() vs millis() — non-blocking code explained with real examples ✅ Writing your own functions — keep your code clean from day one ✅ Serial Monitor tricks — debug like a professional 🛒 COMPONENTS USED: 🔲 ESP32 Development Board AliExpress → https://s.click.aliexpress.com/e/_c2IAMVUX Amazon → https://amzn.to/493Wv5A ⏱️ Video Chapters: 00:00 - Introduction to Arduino Programming Basics 01:04 - void setup() vs void loop() Explained 02:50 - Selecting the Board & Uploading Code to ESP32 06:22 - Measuring Output Voltage with a Multimeter 07:12 - Crucial Tip: 3.3V (ESP32) vs 5V (Arduino Uno) 08:06 - Initializing and Using the Serial Monitor 11:53 - Declaring Variables & Data Types (Int, Bool, Float) 15:38 - Using if/else Conditional Logic in Arduino 19:14 - Understanding and Writing 'for' Loops 21:35 - How to Create Custom Functions 24:34 - Sending & Receiving Commands via Serial Monitor [Contact Me] 🌐 Website: https://iotbhai.io/ 💻 GitHub: https://github.com/ittipu 📘 Facebook: https://www.facebook.com/profile.php?id=61565698329253 📧 Email: [email protected] Like, comment, and subscribe for more Raspberry Pi, Arduino, ESP32, GSM, GPS, Embedded System & IoT tutorials! #esp32 #ota #github #iot #microcontroller #electronics #firmwareupdate #embeddedsystems #esp32projects #arduino #arduinoproject #arduinoprogramming #esp32ota #iotbhai #esp32wifi #raspberrypi
