Arduino code:
#include <TM1637Display.h> const int CLK = 3; //Set the CLK pin connection to the display const int DIO = 2; //Set the DIO pin connection to the display int numCounter = 0; TM1637Display display(CLK, DIO); //set up the 4-Digit Display. void setup() { display.setBrightness(0x0a); //set the diplay to maximum brightness } void loop() { for(numCounter = 0; numCounter < 1000; numCounter++) //Iterate numCounter { display.showNumberDec(numCounter); //Display the numCounter value; delay(1000); } }
