Program: Sensors / Actuators & Data Visualization with Microcontrollers
Description: This html code works in conjunction with the Arduino Uno C++ code
to display a dashboard containing analalog Canvas-Gauge dials and
interactive toggle switches which control actuators.
The web page, along with minimal assets are stored on the MCU's SD card.
Ajax is used to update the analog values of both the Gauges and the
toggle switches associated with the webpage.
