This chapter looks in depth how Arduino components interact with web page elements. You will use analog and digital data, JavaScript data structures, and simple calculations on the data. By the end of this chapter, you will have created an interactive application using potentiometers to answer web-based questions, make calculations with the data, and visualize it on an Arduino.
Analog and Digital Signals
Arduinos have both digital and analog pins that can send and receive either analog or digital signals. An analog signal is continuously variable; a digital signal counts in fixed ...
