Timer Counter Balapan Mini 4WD RACING TAMIYA

Timer Counter Balapan Mini 4WD RACING

        Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat menghitung waktu dalam satuan detik dan milidetik, sehingga dapat diaplikasikan ke balapan mobil mini 4WD atau sejenisnya. untuk lebih jelasnya berikut adalah program dan komponennya.

a. Komponen

b. Program Arduino IDE

#include <Wire.h>

#include <SPI.h>        //SPI.h must be included as DMD is written by SPI (the IDE complains otherwise)

#include <DMD.h>        //Library DMD yang menyediakan fungsi penampilan teks, gambar dsb

#include <TimerOne.h>   //Library peripheral Timer1 untuk menjalankan prosedur pindai panel DMD

#include <Time.h>     //Library waktu yang menyediakan tipe data, struktur, dan obyek waktu

#include "Arial_black_16.h"

#include "Arial_Black_16_ISO_8859_1.h"

#include "Arial14.h"

#include "DejaVuSans9.h"

#include "Droid_Sans_12.h"

#include "Droid_Sans_16.h"

#include "DejaVuSansItalic9.h"

#include "Mono5x7.h"

#include "SystemFont5x7.h"

#define WAKTU_TAMPIL_JAM      10    //detik

#define WAKTU_TAMPIL_KALENDAR 5     //detik

#define DISPLAY_COLUMN_COUNT  2

#define DISPLAY_ROW_COUNT     1

#define PIXELS_PER_COLUMN  32

#define PIXELS_PER_ROW    16

unsigned char show = 0;

char lineBuff[20];

char lineBuff2[20];

int lineA;

int lineB;

int lineC;

int seconds;

int cs;

  dmd.clearScreen( true );   //true is normal (all pixels off), false is negative (all pixels on)

  Serial.begin(9600);

   //initialize TimerOne's interrupt/CPU usage used to scan and refresh the display

  Timer1.initialize( 1000 );           //period in microseconds to call ScanDMD. Anything longer than 5000 (5ms) and you can see flicker.

  Timer1.attachInterrupt( ScanDMD );   //attach the Timer1 interrupt to ScanDMD which goes to dmd.scanDisplayBySPI() 

  //clear/init the DMD pixels held in RAM

  dmd.clearScreen( true );
