Hello readers, I hope you are all doing great. In the previous tutorial, we discussed an inbuilt sensor of the ESP32 that is the Hall sensor. In this tutorial, we will discuss another inbuilt sensor of the ESP32, which is the Capacitive Touch Sensor.
What is a Capacitive Touch Sensor?

Hello reader, I hope you all are doing great.
The ESP32 development board is featured with some inbuilt sensors like a capacitive touch sensor and hall effect sensor. In this tutorial, we are going to discuss one of those inbuilt sensors that is the Hall Effect sensor. Hall Effect sensor is used to ...
Hello readers, I hope you are all doing great. In this tutorial, we are going to discuss the OTA web updater on the ESP32.
We already covered the fundamentals of OTA programming in ESP32, in our previous tutorial where we used the Arduino IDE to upload OTA code into the ESP32 module using the netwo ...
Hello readers, hope you all are doing great. In this tutorial, we are going to discuss a mechanism that allows users to update the ESP32 with a new program wirelessly or over the air (without using a USB cable to upload a new program).
Over-The-Air (OTA) programming

Along with multiple wireless and processing features, ESP32 ...
Hello readers, hope you all are doing great. In this tutorial, we are going to discuss another ESP32 module’s feature that is PWM (pulse width modulation).
We will also explain and demonstrate, how to implement PWM on DC motor and LED using ESP WROOM-32 module.
What is Pulse Width Modulation?

Hello readers, hope you all are doing great. This is our 3rd tutorial in the ESP32 programming series. In our previous tutorial, we discussed the ESP32 Web server, where we created the ESP32 web server in STA mode.
ESP32 can be operated as an access point (AP) or a Wi-Fi station (STA mode). So, in ...
