Introduction: Arduino Light Intensity Lamp Making

The purpose of this project is to create a circuit that turns on at night. This circuit is great for companies, reading at night, and doing other important stuff.



  1. LDR
  2. Arduino microcontroller
  3. lightbulb
  4. Relay
  5. Power source
  6. Breadboard
  7. Resistor

Step 1: Get Your Supplies Ready Around the Bread Board

Step 2: Organize Your Supplies in the Breadboard.

Keep all your supplies gathered in one place first before you start to tinker. Preparation is more important when doing stuff like this.

Step 3: Connect the Wires to the Circuit.

Make sure to connect all the wires effectively and use some kind of colour to define each wire so it all becomes clear to understand for you and others.

1. Connect the Light Bulb's ground end and Connect it to relay Terminal 7. Make sure Terminal 8 is connected to the ground train. Then attach the Relays Terminal 5 to some Wireless Pins.

Step 4: Create a Text Code for the Circuit to Work.

The goal here is for you to understand the need for a relay in this circuit and to be able to write your own Arduino code.

Step 5: Finished!

Of course after following all the write steps you arrive at your final image which is the light bulb turning on.

Note; You can control the bulb by using the LDR.
