C7: Arduino Basics & I/O with Tinkercad Circuits

Aim:
 To build a light that turns ON in the dark using an Arduino and LDR.

Requirements:

  • Arduino Uno

  • Breadboard

  • LDR (Light Dependent Resistor)

  • LED

  • 220Ω resistor (for LED)

  • 10kΩ resistor (for LDR voltage divider)

  • Jumper wires

  • Tinkercad Circuit (or real components)

Steps:

  1. Open Tinkercad and create a new circuit.

  2. Connect the LDR and 10kΩ resistor in series between 5V and GND. Connect their middle junction to analog pin A0.

  3. Connect the LED’s anode to digital pin 9 with a 220Ω resistor, and cathode to GND.

  4. In Code Blocks or Arduino IDE, write a program:

    • Read the analog value from the LDR.

    • If the value is below a threshold (i.e., it’s dark), turn LED ON.

    • Else, keep it OFF.

  5. Test your setup: cover the LDR with your hand to simulate darkness. The LED should turn ON!
