Timer Counter Board Mini 4WD 3 Jalur Line / Track

 Timer Counter Board Mini 4WD 3 Jalur Line / Track 

        Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang bisa digunakan untuk counter timer untuk balapan mobil mini 4WD, jadi alat ini menggunakan 3 buah sensor sesuai dengan jumlah track yang dipakai kemudian terdapat 3 lap sehingga jika ada yang telah mencapai 3 lap terlebih dahulu dialah yang menang. untuk lebih jelasnya berikut adalah koding dan komponennya.

 

a. Arduino Uno


b. Sensor Proximity


c. Koneksi Arduino ke P10 HUB12



d. 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
