Aim:
To explore the Arduino Uno board virtually and learn about its key parts.

Requirements:

• Computer with internet access

• Tinkercad account (free)

Steps:

1. Log into Tinkercad

   • Open Tinkercad in your web browser.

   • Sign in with your account and go to Circuits from the main menu.

2. Start a New Circuit

   • Click Create New Circuit.

   • A blank workspace will appear.

3. Add an Arduino Uno

   • On the right-hand side, search for Arduino Uno in the components menu.

   • Drag and drop it into your workspace.

4. Observe the Arduino Uno Board
   Carefully look at the different parts of the board:

   • USB Port – Used to connect the Arduino to the computer for coding and power.

   • Power Pins – Provide electricity (5V, 3.3V, and GND/ground).

   • Digital Pins (0–13) – Work like on/off switches, used for sensors and outputs.

   • Analog Pins (A0–A5) – Measure varying signals, like light brightness or temperature.

   • Reset Button – Restarts the program inside Arduino.

   • Power Jack – Connects an external power supply if not using USB.

5. Hover for Labels

   • Move your mouse over each pin.

   • Tinkercad shows the pin label and what it does.

6. Note Key Sections

   • Make notes about which pins are for inputs (sensors) and which are for outputs (like LEDs or motors).

   • For example: “Analog pins read values, Digital pins switch things ON/OFF.”
