We all love to build IoT projects based on ESP32 boards because it has lots of GPIO pins to play. Many ESP32 lovers like me face a problem selecting appropriate GPIO pins or which pins to avoid for their projects.

We have wasted many hours on an ESP32 project due to the selection of the wrong GPIO pin and, we don’t want you all to be making the same mistake.

Therefore we have created this easy-to-use guide, simplifying the ESP32 GPIO selection process. If you use a bar ESP32 module in your project, this guide will be a handy tool for you.
For most of us, ESP32 is the first preference for our IoT projects. Due to its advanced functionality with simple usage.

Among all the functionality, we will be discussing one of them today, which will take your IoT project to the next level.
Are you bored with your small 16×2 LCD? As I am. Therefore we have come up with a tutorial for jumbo LCD 16×2.

This LCD display is a perfect choice if your project needs easy readability. In this tutorial, we will learn how to interface this jumbo LCD with Arduino UNO.

You will learn how to hook up this jumbo LCD for your upcoming project. We will be using an I2C interface with the jumbo LCD.
Changing Wi-Fi credentials in code for your ESP32 based IoT project is frustrating, right?

As most of us, either hard code Wi-Fi credential or will use famous Wi-Fi manager.

Apart from this, there is a method known as ESP-Touch, and it works on SmartConfig technology developed by TI.

We will explore SmartConfig technology, and you will be amazed as it is super simple to use and lightweight.

We will be using Arduino IDE for programming ESP32.
If you never used an oscilloscope before then, this project is for you. Thanks to the project scoopy, now we can use our Pi-Pico board to build our oscilloscope. This oscilloscope is a great start towards exploring your electronics project insides. This project can be the cheapest way to own a digital oscilloscope. Let’s explore what can be done with this.
Recently Raspberry pi foundation has launched the Pi Pico microcontroller board. This board had quickly gained the attention of the community due to its low cost and high performance.
In this tutorial, we will explore the Pi Pico board and, we will learn to program it using Arduino IDE.
WhatsApp is now an essential part of our day-to-day life. Receiving any alert messages from ESP32 directly to WhatsApp would be great.
Therefore in this tutorial, we will show you how to send any messages directly to your WhatsApp.
We will be using Arduino IDE for programming ESP32.
In this learning guide, you will learn about Operational Amplifiers (OP-AMP). Operational amplifiers are a fundamental part of analog electronics. Learning characteristics and knowing different usage of operational amplifiers can help you get started with opamp-based projects. Stick around with us in this analog journey of an OP-AMP.
ESP32-CAM has everything to build your camera-based IoT projects. But the major disadvantage of the ESP32-CAM board is that it does not have a USB programming connector or any power connector.
For programming an ESP32-CAM board, we have to connect with FTDI converters, and it also doesn’t have an onboard auto-reset circuit.
Want to explore IoT projects? Then learning ESP32 is a great starting point. In this tutorial, you will learn how to install ESP32 in Arduino IDE. We will use Windows for this tutorial, but the same steps can be used for, mac and Linux OS.
To program ESP32, we have to add an addon package in Arduino IDE.
