In this tutorial we will learn how to use placeholders to replace values at run time in a HTML file served from the ESP32 file system. We will be using the ESP32 async web server library and the Arduino core. The tests shown here were performed using a DFRobot’s ESP32 module integrated in a ESP32 development board.
In this tutorial we will check how to use multiple placeholders in the template processing engine of the HTTP async libraries for the Arduino core, running on the ESP32. The tests were performed using a DFRobot’s ESP32 module integrated in a ESP32 development board.
