Keep It Up!

Are you tired of losing focus while working or studying? Do distractions keep stealing your productivity away? Well, worry no more! Introducing the revolutionary Keep it Up!™ The gadget that rewards your dedication and mocks your procrastination!

Simply sit in front of the small box featuring an ultrasonic sensor and stay in the focus zone. If you manage to focus for the set amount of time, the Keep it up!™ will inform you of your good work by celebrating alongside you! Don't procrastinate though! Leave your desk for too long and Keep it up!™ will deliver a slow, sarcastic clap, letting you and everyone everyone around you aware of your failures!

1. Arduino Uno
2. ULN2003 Stepper Motor Driver Board
3. 28BYJ-48 Stepper Motor
4. HC-SR04 Ultrasonic Sensor
5. Jumper Wires x 15
6. 9V Battery + Barrel Jack
7. Mechanical Arm/Clapper Attachment
8. Box (plywood or cardboard)
9. Hands (plywood or cardboard)
10. Rubber Bands
11. dowels x2

Step 1: Connect the Motor to the Driver

1. Plug the stepper motor’s 5-wire connector into the ULN2003 driver board.
2. All 5 wired should connect to the driver board
3. The LEDs should blink when powered

Step 2: Connect Driver to Arduino

Connect control wires:

1. IN1 into Arduino pin 8
2. IN2 into Arduino pin 10
3. IN3 into Arduino pin 9
4. IN4 into Arduino pin 11
5. The positive 5-12v into Arduino 5v
6. The negative 5-12v into Arduino ground

Step 3: Connect the Ultrasonic Sensor

1. VCC into Arduino Vin
2. GND into Arduino GND
3. Trig into Arduino pin 2
4. Echo into Arduino pin 3
5. This should detect the distance of the user

Step 4: Power

1. Plug 9V battery into Arduino barrel jack.
2. ULN2003 gets power from Arduino (or external supply if needed).
3. The Vin pin gets power from the external 9v battery pack

Step 1: Motor library

1. Import the motor library into the code

Step 2 : Assign variables

1. Declare names, types and values to every variable

Step 3: Setup function

1. Set sensor pins as input/output.
2. Set default motor speed.

Step 4: Get Distance Function

1. Send a pulse from trig.
2. Measure echo time.
3. Convert time to distance.
4. Return the distance.

Step 5: Main loop

1. Measure distance.
2. Sets the baseline distance
3. Compares current distance to baseline.
4. If user stays within tolerance:
5. Start timer.
6. If timer reaches 60 seconds, run win function.
7. If user leaves:
8. Start leave timer.
9. If gone too long , run slow clap.

Step 6: Make a win function

1. Increase motor speed.
2. Move forward.
3. Move backward.
4. Repeat a few times.
5. This will make the physical hands clap in a genuine way

Step 8 — Make a lose function

1. Lower motor speed.
2. Smaller movement.
3. This will make the physical hands clap in a slow, sarcastic way
