ESP32 capacitive touch sensor, What is a capacitive touch sensor and how does it work, Capacitive touch sensor in ESP32, Programming capacitive sensor in ESP32, Code for touchRead, Testing, Code description, Serial monitor, Loop(), Setup()

Hello readers, I hope you are all doing great. Welcome to the 2nd lecture of Section 5(ESP32 Sensors) in the ESP32 Programming Series. In the previous tutorial, we discussed the built-in ESP32 Hall Effect Sensor. In this tutorial, we will discuss another inbuilt sensor of the ESP32 i.e. Capacitive Touch Sensor. ESP32 Board has 10 built-in capacitive touch pins, which generate an electrical signal when someone touches these pins. These ESP32 touch pins are normally used to wake up the board from deep sleep mode. These touch pins are also used to replace the normal mechanical buttons with tou ...

ESP32 OTA web updater, Code for OTA web updater implementation in ESP32, Code description, Serial monitor, Testing, Test code, Test code description, How to generate a bin file, LED blink

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 network port. In the OTA web updater, you need to create a web server page for OTA programming.
