✅ Officially Supported Arduino Libraries in Tinkercad Circuits:

1. Servo.h 🤖🦾

• Purpose:
  Control standard servo motors.
• Functions:

#include <Servo.h>
Servo servo; 
servo.attach(pin);
servo.write(angle);

2. LiquidCrystal.h 📺✨

• Purpose:
  Interface and control LCD displays (16×2, 20×4, etc.).
• Functions:

#include <LiquidCrystal.h>
LiquidCrystal lcd(RS, E, D4, D5, D6, D7);
lcd.begin(16,2);
lcd.print("Hello");

3. SoftwareSerial.h 🔄📡

• Purpose:
  Create additional software-based serial communication ports.
• Functions:

#include <SoftwareSerial.h>
SoftwareSerial mySerial(RX, TX);
mySerial.begin(9600);
mySerial.println("Hello");

4. Stepper.h 🛞⚙️

• Purpose:
  Control stepper motors (28BYJ-48 and others).
• Functions:

#include <Stepper.h>
Stepper stepper(stepsPerRev, pin1, pin2, pin3, pin4);
stepper.setSpeed(60);
stepper.step(steps);

5. EEPROM.h 💾📝

• Purpose:
  Read and write data to Arduino’s built-in EEPROM memory.
• Functions:

#include <EEPROM.h>
EEPROM.write(address, value);
EEPROM.read(address);

🚩 Libraries Not Supported:

Tinkercad does not support custom or external libraries. You cannot upload or include your own libraries (e.g., FastLED, Adafruit_Sensor, etc.).

Example of unsupported use:

#include "CustomLibrary.h"  // ❌ Not supported!

#include <Wire.h>           // ❌ Not supported (no I2C devices)!

#include <SPI.h>            // ❌ Not supported!
