Introduction: Arduino Relay Activated Lamp
In this tutorial you will be able to make a relay activated lamp using code.
We will be using tinkercad for this project and the following devices will be needed:
Step 1: Set Up the Breadboard
Copy the image above as it will allow you to add in more features such as the LDR and relay.
Step 2: Add in the LDR and 1k Resistor
Add in the LDR and resistor into the circuit and wire it properly.
Step 3: Add in the Relay
You will now need to add in the relay into the circuit as shown in the image. Make sure the wires line up with the right point on the relay.
Step 4: Add in the Light Bulb
Add the light bulb into the circuit as shown in the image. It should be connected to the point on the relay
Step 5: Add in the Power Source
Add in the last component to complete the circuit. Make sure the entire circuit is wired properly.
Step 6: Code
The code shown in the image is what you will need to make your project work effectively. The light bulb will only turn on when the LDR sensor determines that it is dark.
