Interface and Application Programming is an important part of embedded systems development. It allows a computer or application to communicate with a microcontroller board such as Arduino, ESP32, or RP2040. Through this communication, users can send commands, receive sensor data, display information, and create interactive systems.

In this group assignment, different software tools used for communication between embedded boards and computers were studied and compared. The tools analyzed were:

• Arduino IDE Serial Monitor
• Python with PySerial and Tkinter
• Processing
• Web Serial API

These tools are commonly used in digital fabrication, IoT projects, and Fab Academy assignments.

2. Objective of the Group Assignment

The objectives of this assignment were:

• To understand how interface and application programming tools communicate with embedded boards.
• To compare different tools based on usability, features, flexibility, and complexity.
• To identify which tools are suitable for beginners and advanced users.
• To learn different workflows for serial communication and visualization.
• To explore methods for building graphical user interfaces (GUIs) and web-based interfaces.

4. Typical Workflow of Each Tool

void setup() {
  Serial.begin(9600);
}

void loop() {
  Serial.println("Hello from Arduino");
  delay(1000);
}

import serial

arduino = serial.Serial('COM4', 9600)

while True:
    data = arduino.readline().decode().strip()
    print(data)

import processing.serial.*;

Serial myPort;

void setup() {
  myPort = new Serial(this, "COM4", 9600);
}

void draw() {
  if (myPort.available() > 0) {
    String data = myPort.readStringUntil('\n');
    println(data);
  }
}

const port = await navigator.serial.requestPort();
await port.open({ baudRate: 9600 });
