In this guide, you’ll learn what the ESP32 is, why it’s better than Arduino for modern DIY projects, and how Techsage’s Innovator Box leverages the power of ESP32 to make learning electronics both fun and futuristic

Introduction to ESP32 for Beginners: Why It's the Future of DIY Electronics

If you're just starting your journey into electronics and circuit building, you've probably heard the term "breadboard" being thrown around.

What is a Breadboard and How Does it Work? A Beginner's Guide

In this project, we’ll connect an LED to an ESP32 using a breadboard and jumper wires to make it blink. This is a perfect beginner project to understand basic GPIO pin functionality on the ESP32.

Project 1: Getting Started with ESP32

This project demonstrates how to use an LDR (Light Dependent Resistor) to detect light levels and control an LED. When the light level falls below a certain threshold, the LED turns on, and when it rises above the threshold, the LED turns off.

Project 2: Automated Night Light Using LDR

This project demonstrates how to use an ESP32 with an LDR (Light Dependent Resistor) module, a laser module, and a buzzer to create a simple security system. The system detects changes in light intensity using the LDR and triggers an alarm when the light beam is interrupted.

Project 3: Laser Tripwire using Laser Module and LDR

This project demonstrates how to use an ESP32, an ultrasonic sensor (HC-SR04), a buzzer, and an I2C LCD to create a proximity alert system. The system continuously measures distance using the ultrasonic sensor, displays it on an LCD, and triggers a buzzer when an object comes too close.

Project 4: Distance Alert Display Using Ultrasonic Sensor & LCD

In this tutorial, we will create a simple circuit and code that shows a message on an LCD screen when a button is pressed. The message toggles between two different texts on the LCD each time the button is pressed.

Project 5: Dino Game on LCD

In this tutorial, we will create a simple web server using the ESP32 that allows us to control two LEDs from a smartphone or any device connected to the Wi-Fi network. This project does not use resistors, as we are directly connecting the LEDs to the ESP32.

Project 6: ESP32 Wi-Fi Led Control Tutorial

In this tutorial, you'll create a wireless servo motor controller using an ESP32. You'll be able to control a servo motor through a web interface on your phone or computer - no external WiFi network needed!

Project 7 :  Servo Control Wirelessly

This project creates a radar system using an ESP32 microcontroller, ultrasonic sensor, servo motor, and a visual display on your computer. The radar sweeps in a 180-degree arc, detecting objects and displaying them on a colorful radar screen - just like in movies!

Project 8 : Ultrasonic Radar using Servo and ESP32

This project uses an ESP32, an IR sensor, and an I2C LCD to count the number of objects passing in front of the sensor. It includes debouncing for accuracy, serial commands for testing and resetting, and a real-time LCD display.

Project 9 : IR Sensor Object Counter with ESP32 &  LCD

In this tutorial, we will build an RC car that can be controlled via a Wi-Fi-based web interface using an ESP32. The car will have forward, backward, left, and right movement controls, along with a speed control slider.
