RickRoll Police

What's a better way to start than RickRolling ?
I enjoyed going through a lot of Projects on Instructables.
While some required you to have access to high end tools and supplies, I thought to start with something more creative right from the supplies you'll easily have at home.

IDEA:

To build a Police Bot, That rickrolls Intruders.

• LEDs
• 9V Battery
• Jumper Cables
• Photoresistor (LDR)
• Old Speaker / Piezo Buzzer
• Arduino UNO (Microcontroller)
• Breadboard (Small or medium)
• Resistors (10k Ohms & 220 Ohms)
• Crocodile Clips / Solder Iron (Optional)
• Cardboard
• A4 sheet
• Markers, Scissors etc for decoration
• Laser (just for fun)

The Best approach to building a project is making the prototype.
For this I used Tinkercad.
It helped me make the failproof circuit, decide on the resistance of the resistors to avoid damaging circuit components due to high voltage.
I started by adding a Breadboard and Arduino Uno to the canvas, you can feel free to use any of the starters.

• First, I created a simple buzzer
• Then I figured out the tones for the Rick Rolling
• Then, I added LEDs
• Then I wrote Code to synchronize the LEDs to glow with par to the music played
• Then I added a photoresistor
• I used it to act as a switch, Which starts the circuit when it reads sufficient light from the atmosphere

The Idea being That our RickRoll Police Bot will guard an object / Item.
If and When the object is displaced from its place, Light will fall on the sensors,
Which It will detect and start to Rickroll the Intruder

Component List

As someone just getting started, I can understand the complexity of the circuit involved in the project.
I too, had to reference a lot of information to get things right.
But you need not worry, Just follow this Instructable, and you can build your own RickRolling Police Bot!

See above the Circuit Schematics.
Use a breadboard and make the Connections

Incase you wish to change the pins, you can simply change the variables for the same in the code

Now the code,

Don't you worry,
You can code it yourself without much trouble using Coding blocks on Tinkercad.
Nevertheless, I have attached my Code which you can use !

You might need to still give some time calibrating your LDR, and even changing the threshold in the code if at all required.

That's it, halfway DONE!

Use your Cardboard Box, that is where we will fit the Breadboard.

I carefully cut out the Instructables Mascot Robot Design from a plain sheet of A4. I then Covered The Cardboard box with Black paper. Then I stuck the Mascot design on it, pierced holes through his eyelids to insert The LEDs. I put in the Light Dependent Sensor in the kite. I then fit in the rest, Breadboard, Speaker, Battery, Arduino, and made the connections.

Now I tested the RickRoll Police, to determine If I was successfull in building it.
I did this by shinning a laser beam on the kite which the RickRoll Police held in it's right hand.

The RickRoll Police responded to the light, and started Rick Rolling!

MISSION SUCCESSFULL !

Watch RickRoll Police on Duty,
Guarding my Cardboard Creation from the Hands of Intruders.
