ESP32 Web Server with DS18B20 and Max7912 7segment display Interface
In this tutorial, we will learn how to create a temperature monitor using the DS18B20 digital temperature sensor, an ESP32 web server, and a MAX7912 8-digit 7-segment display.
The ESP32 will be used to host a web server that presents temperature readings directly on a webpage, which can be accessed through any standard web browser. The DS18B20 sensor will provide temperature data, and the MAX7912 will drive an 8-digit 7-segment display. The display will be divided into two 4-digit sections: one for Celsius readings and the other for Fahrenheit.
