Computer Prank With Arduino

This is an instructable to make a crappy robot that turns off your laptop when you go in front of it and just to piss you off turns it on when you go away.

Step 1: Materials Needed

To make this robot you will need :

• Arduino board
• an ultrasonic sensor
• a servo motor for Arduino
• Masking tape
• a computer
• wires
• scissors
• a breadboard

Step 2: Wiring the Ultrasonic Sensor

• Insert the ultrasonic sensor into the breadboard.
• Connect the trig pin to digital port 8 and the echo pin to port 7.
• Connect the 5V to the 5V line in the breadboard and the GND to the GND line in the breadboard.
• Connect these two lines to the board (5V to 5V and GND to GND).

Step 3: Wiring the Servo Motor

Connect the servo motors three wires to the 5V on the breadboard, GND on the breadboard and digital port 9 respectively.

Step 4: Setting the Robot Up

• Tape the motor to the computer such that the motor will be able to push the power button.
• The end of the motor should be facing the screen of the laptop.
• Place the ultrasonic sensor facing where you expect a person to be standing when he is trying to work on the computer (like in the picture).

Step 5: The Code

Step 6: Final Step

Upload the code to the board and you should have your own crappy robot.
