ELECTRONICS 101 : ARDUINO, SENSORS, ESP32 AND PROCESSING

1. During this series of hands-on classes at FABLAB UPSaclay you will learn the basics of Arduino and explore the world around you through the use of electronic sensing devices (sensors). You will investigate and document :

• 1. The Arduino Hardware (PCB) and Software (IDE).
• 2. Some sensors (or input devices) in combination with Arduino.
• 3. The ESP32 hardware in combination with the Arduino IDE.
• 4. The Processing software in combination with the Arduino UNO board and/or the ESP32 board.

[ASSIGNMENT TO BE DONE ON ] : 11/28/2022 AND ON 12/12/2022

• A) Find the Arduino UNO’s “Specification Sheet” on the web, read it, and explain what it does in 5 lines (max).
• B) Connect an Arduino UNO to a sensor. Program it. Read the data coming out of it through the Serial Monitor and through the Serial Plotter.
• C) Generate a Graphical User Interface in Processing to express visually the data coming from your sensor.
• D) Repeat the steps with the ESP32 (IoT board with integrated wi-fi) to send your the data coming from your sensor to a localhost page.

[EXTRA ASSIGNMENT] :

• Create an app that interfaces with the ESP32 to send its data online.

2. Arduino is a system composed of open hardwares and open source softwares. Designed for Education, you can use all the ressources provided by Arduino for free. You just need an Arduino Circuit Board to connect to your computer and to install the Arduino IDE on your computer (free as well). The Fablab will lend you an Arduino Uno V3 for the time of the course.

3. Arduino can be connected to various sensors. You can sens many things like temperature, humidity, distances, proximity, colors, particules, motion, light, infra-reds, force, air quality, co2 and other gazes, speed, etc.

4. With a simple light-sensor you can get data out of the Arduino board through the Serial Monitor (see the numbers above) that is embeded into the Arduino IDE or from the Serial Plotter (see the curves above).

5. With the Processing app, you can easily create a GUI (Graphical User Interface) to visualize creatively the data coming out of the combination of the light-sensor and the Arduino Uno board.

6. Here is how the combination of the Arduino board and the light-sensor looks like.

unsigned int ADCValue;
void setup(){
    Serial.begin(9600);
}

void loop(){

 int val = analogRead(0);
   val = map(val, 0, 300, 0, 255);
    Serial.println(val);
delay(100);
}

7. Here is the code that you copy/paste into the Arduino IDE, to transfer to the Arduino board.

import processing.serial.*;

Serial myPort;  // Create object from Serial class
static String val;    // Data received from the serial port
int sensorVal = 0;

void setup()
{
   size(720, 480);
   noStroke();
  noFill();
  String portName = "/dev/cu.usbmodem14201";// Change the number (in this case ) to match the corresponding port number connected to your Arduino.

  myPort = new Serial(this, portName, 9600);
}

void draw()
{
  if ( myPort.available() > 0) {  // If data is available,
  val = myPort.readStringUntil('\n');
  try {
   sensorVal = Integer.valueOf(val.trim());
  }
  catch(Exception e) {
  ;
  }
  println(sensorVal); // read it and store it in vals!
  }  
 background(0);
  // Scale the mouseX value from 0 to 640 to a range between 0 and 175
  float c = map(sensorVal, 0, width, 0, 400);
  // Scale the mouseX value from 0 to 640 to a range between 40 and 300
  float d = map(sensorVal, 0, width, 20,1600);
  fill(255, c, 0);
  ellipse(width/2, height/2, d, d);   

}

8. Here is the code that you copy/paste into the Processing IDE, to generate this GUI.

11. The ESP32 FIREBEETLE V1.0 we have are from DFROBOTS. In the pictures below, you will learn how to make a web-server to control 2 LEDs through a wifi-connection with the FireBeetle. Now that you know how to use the ARDUINO IDE, you can start with the ESP32 and explore the web to find projects you like. But first, reproduce the steps below to make a web-server.

12. You can even play with the HTML from the html code that is embedded into the Arduino code. You can change the apparence of the interface to make it fit your taste, like I did below.
