Arduino Serial Plotter – look at analog inputs

Code – copy and paste into IDE then Save As 6InputSerialPlotter

/*6InputSerialPlotter
 * Arduin0 – Serial Plotter 4 is Created by ArduinoGetStarted.com
* modified by Don Allen to show 6 analog input traces or plots 15 June 2020.
*
* The example code for the 4 input analog plotter is in the public domain
* I have added analog inputs 5 and 6.Note that the Serial plotter program added two extra coloured traces.
*
* Use your breadboard to connect one leg of your LDR to +5V, the other leg of the LDR to one leg of a 47K resistor, the other leg of the 47K resistor to Ground,
* use a jumper wire to connect the junction of the LDR and 47K resistor to each of the analog inputs A0 – A5
* Spread your LDR’s as far apart as you can, so covering one LDR does not affest the other 5 LDR’s.
* Uploard this sketch to your Arduino, run the Serial Plotter Tools > Serial Potter or Control+Shift+L and you can see the LDR values change as you cover them up.
* With no LDR inputs covered, the six traces are spaced by their noise values, when you conver an LDR the Y axis scale changes and you see a large excursion and the other 5 traces compress.
*
* X-axis: represent the time. It has 500 points. The time between each point is the time between two consecutive Serial.println() function calls. This time is usually equal to the time of loop() function.
* Y-axis: represents the values received from Arduino. The Y-axis automatically adjusts itself as the value increases or decreases.
