My inspiration for this project came from a lecture where they showed someone who created a basketball game as their final project. I often get bored and love playing games, so I decided to make my own version using paper balls, which are always around. This makes it simple, fun, and easy to play anytime.

Input Actions :
Paper Ball Hits Near the Ultrasonic Sensor : sensor detects the object
No paper detected : nothing happens
push button --> to reset score
Output Actions :
When paper ball is detected (point scored)
-LED blinks & score increases on LCD
No paper detected : LED remains ON & LCD score is the same
Wiring on TinkerCad (same wiring on real life ) on tinkercad use the default wiring they have for the lcd
Connections
LCD I2C :
GND --> GND ( Arduino )
VCC --> 5V
SDA --> A4 (default)
SCL --> A5 (default)
Ultrasonic Sensor
VCC --> 5V
Trig --> pin 3
Echo --> pin 4
GND --> GND
LED
Anode --> pin 7
Cathode --> GND
Push button
terminal 1 --> pin 8
terminal 2 --> GND

Wiring on Breadboard
Arduino Code
Declare pin locations:
Assign pin numbers for the ultrasonic sensor (trig & echo pins), LED, and reset button.
Setup section void setup ()
Set pin modes (e.g., LED as output, ultrasonic sensor pins, and reset button as input with INPUT_PULLUP
Initialize the LCD and display "Score: 0".
Turn the LED ON by default to indicate the system is active.
Loop section void loop ()
Reset button functionality:
Uses if statements to check if the reset button is pressed.
If pressed, it resets the score to zero and updates the LCD.
Ultrasonic sensor detection:
Uses digitalWrite(trigPin, HIGH) to send a pulse.
Echo pin reads the returning pulse to measure distance.
If a ball is detected within the scoring range, the score increases and is displayed on the LCD.
LED behavior:
Blinks when a score is registered.
Stays ON when waiting for a score.

My biggest challenge with the cardboard enclosure was extending the wires—something always seemed to stop working whenever I tried. After some trial and error, I finally got everything to work.
A useful tip: Masking tape is essential for successfully extending wires! It helps secure the connections and prevents loose or faulty wiring.
For the LCD wiring, I wasn’t sure how to set it up correctly, so I looked it up on Google and found a helpful guide https://lastminuteengineers.com/i2c-lcd-arduino-tutorial/

For the code, I had it mostly working but needed a few adjustments. I used ChatGPT to help fix and fine-tune it.
