Course Introduction

In this lesson, you’ll learn how to build a simple basketball score counter using an Arduino, an IR obstacle avoidance sensor, and a TM1637 4-digit display.

This experiment simulates real-time scoring by detecting each successful shot and automatically updating the score on the display.

Writing the Code

Note
You can copy this code into Arduino IDE.
To install the library, use the Arduino Library Manager and search for TM1637Display and install it.
Don’t forget to select the board(Arduino UNO R4 WIFI) and the correct port before clicking the Upload button.

#include <TM1637Display.h>

// TM1637 pins
const int CLK_PIN = 9;
const int DIO_PIN = 8;

// IR sensor pin
const int IR_PIN = 2;

// Create display object
TM1637Display display(CLK_PIN, DIO_PIN);

// Score value
int score = 0;

// Sensor states
bool lastSensorState = HIGH;

// Anti-double-count timing
unsigned long lastScoreTime = 0;
const unsigned long cooldownTime = 800;  // ms

void setup() {
  // IR sensor input
  pinMode(IR_PIN, INPUT);

  // Set display brightness (0-7)
  display.setBrightness(7);

  // Show initial score
  display.showNumberDec(score, true);

  // Read initial sensor state
  lastSensorState = digitalRead(IR_PIN);
}

void loop() {
  bool currentSensorState = digitalRead(IR_PIN);

  // Count only when sensor changes from unblocked to blocked
  // Many IR obstacle modules output LOW when obstacle is detected
  if (lastSensorState == HIGH && currentSensorState == LOW) {
    if (millis() - lastScoreTime > cooldownTime) {
      score++;

      // Limit display range to 9999
      if (score > 9999) {
        score = 9999;
      }

      display.showNumberDec(score, true);
      lastScoreTime = millis();
    }
  }

  lastSensorState = currentSensorState;
}
