C7: Arduino Basics & I/O with Tinkercad Circuits

Aim:
To write a simple block code that makes an LED blink using Arduino in Tinkercad.

Requirements:

  • Tinkercad Circuit

  • Arduino Uno

  • Breadboard

  • LED

  • 220Ω resistor

  • Jumper wires

Steps:

  1. Open Tinkercad and go to Circuits → create a new circuit.

  2. Place components: Drag an Arduino Uno, LED, resistor, and breadboard.

  3. Connect the circuit:

    • Connect LED anode (long leg) to digital pin 13 via a 220Ω resistor.

    • Connect LED cathode to GND.

  4. Open the Code panel and switch to Blocks.

  5. Add these blocks in order:

    • set pin 13 to output (in Setup)

    • set pin 13 HIGH (turn LED ON)

    • wait 1 second

    • set pin 13 LOW (turn LED OFF)

    • wait 1 second

  6. Press Start Simulation to watch the LED blink!
