Unit 11: Digital Numbers

Code for Sketch One:

// Define the connections pins for the TM1637 4-digit display
#define CLK 3
#define DIO 2
 
GyverTM1637 display(CLK, DIO);
 
// Define the button pin

// Variable to count button presses

// Variable to store the button state
int lastButtonState = HIGH;
 
void setup() {
  // Initialize the TM1637 display
  display.clear();
  display.brightness(7);  // Set brightness to maximum
  
  // Initialize button pin as input with internal pull-up resistor

  // Display initial count
