Activity based on LDR sensor Copy


Let’s Learn to interface LDR sensor with Arduino Uno.


Circuit Designing

1. Open the default screen of tinkercad circuit designing.

2. Now, search for Arduino Uno in the search bar and then drag and drop it in the “designing area”.



3. Now drag and drop all the components required in the ” designing area”.

Components Required

  1. Arduino Uno 

  2. LED

  3. 220 ohm Resistor

  4. 4.7 k ohm Resistor

  5. LDR

  6. Breadboard

4. Now, connect all the components as per the circuit diagram and pin connection given below:
