An online oscilloscope made by using p5.js by Processing.org.
The oscilloscope works by taking input from a serial graph and plotting it.
The input must be in the format:
a9b9c9d9
Using this format the plotter can draw up to 4 graphs at once
The value between a & b is value for graph 1
The value between b & c is the value for graph 2
The value between c & d is the value for graph 3
The value after d is the value for graph 4
Note: The value doesn't have to be a single digit
