ChatGPT Arduino Accelerating Blinky, Attempt #1

/* Me: write me Arduino code for a device which blinks an LED and makes the blink rate faster each time a button is pressed */

/* ChatGPT: Here is an example of Arduino code that will blink an LED and increase the blink rate each time a button is pressed: */

const int buttonPin = 2;    // pin for the button
const int ledPin = 13;      // pin for the LED
int blinkInterval = 1000;   // interval at which to blink (milliseconds)

// variables for tracking the button state
int buttonState = 0;    // current state of the button
int lastButtonState = 0; // previous state of the button

void setup() {
  // set the LED pin as output
  pinMode(ledPin, OUTPUT);
  // set the button pin as input
  pinMode(buttonPin, INPUT);
}

void loop() {
  // read the button state
  buttonState = digitalRead(buttonPin);
  // check if the button state has changed
  if (buttonState != lastButtonState) {
    // check if the button is pressed
    if (buttonState == HIGH) {
      // decrease the blink interval
      blinkInterval = max(blinkInterval - 100, 100);
    }
    // save the current button state as the last button state
    lastButtonState = buttonState;
  }
  // turn the LED on
  digitalWrite(ledPin, HIGH);
  // delay for the specified interval
  delay(blinkInterval);
  // turn the LED off
  digitalWrite(ledPin, LOW);
  // delay for the specified interval
  delay(blinkInterval);
