Serial Monitor and Serial Plotter tool on IDE are used not only for debugging but also for monitoring.It is inconvenient to use these tool for monitoring because :
  • Available on PC only. => NOT mobility
  • MUST connect PC to Arduino via USB to Serial cable => short distance

Using Web Serial Monitor and Web Serial Plotter:
  • Available on any PC, Smart Phone and Tablet, as long as web browser is available => mobility
  • Connect via WiFi => unlimited distance (via Internet)
  • NOT required installing any software/app

How To
  • Stack PHPoC Shield 2 or PHPoC WiFi Shield 2 on Arduino
  • Install Arduino library for this shield
  • Upload WebSerialPlotter example to Arduino
  • Open Web Browser and type IP address of PHPoC Shield. It looks like below
  • Click "Web Serial Monitor" and "Web Serial Plotter" one by one, we will see Serial Monitor and Serial Plotter on mobile phone as below

More detail about Web Serial Monitor and Web Serial Plotter.


// Arduino Web Serial Plotter
// PHPoC Shield and PHPoC WiFi Shield are Internet Shields for Arduino Uno and
// Mega.
// These Shields have the buit-in web server and WebSocket server. These Shields
// contain some buit-in embedded web apps. One of the buit-in embedded web apps
// is "Web Serial Plotter". Web Serial Plotter is similar to Serial Plotter on
// Arduino IDE, except for the following points:
//   - Web Serial Plotter is accessed on web browser through Internet (Serial
// Plotter is accessed on Arduino IDE through USB cable).
//   - Web Serial Plotter can be accessed from any OS (Android, iOS, Windows,
// macOS, Linux...) without any installation.
//   - Web Serial Plotter is easily customizable via a setting page.
// This example code shows how to use "Web Serial Plotter".
// Arduino communicates with PHPoC [WiFi] Shield via pins 10, 11, 12 and 13 on
// the Uno, and pins 10, 50, 51 and 52 on the Mega. Therefore, these pins CANNOT
// be used for general I/O.
// This example code was written by Sollae Systems. It is released into the
// public domain.
// Tutorial for the example is available here:

#include <Phpoc.h>

float y1;
float y2;
float y3;

void setup() {
  // initialize PHPoC [WiFi] Shield:

void loop() {
  for(int i = 0; i < 360; i += 10) {
    y1 = 2 * sin(i * M_PI / 180);
    y2 = 3 * sin((i + 90)* M_PI / 180);
    y3 = 5 * sin((i + 180)* M_PI / 180);

    Serial.print(" "); // a space ' ' or  tab '\t' character is printed between the two values.
    Serial.print(" "); // a space ' ' or  tab '\t' character is printed between the two values.
    Serial.println(y3); // the last value is followed by a carriage return and a newline characters.
