3. Langkah Kerja

- Siapkan alat dan bahan yang dibutuhkan
- Buat program pada Arduino IDE seperti berikut ini:

int A = 2;
int B = 3;
int C = 4;
int D = 6;
int DP = 5;
int E = 7;
int F = 8;
int G = 9;

int switchUpPin = 13;
int switchDownPin = 12;
int counter = 0;
int buttonUpState = 0;
int lastButtonUpState = 0;
int buttonDownState = 0;
int lastButtonDownState = 0;

void setup()
{
Serial.begin(9600);

pinMode(A, OUTPUT);
pinMode(B, OUTPUT);
pinMode(C, OUTPUT);
pinMode(D, OUTPUT);
pinMode(E, OUTPUT);
pinMode(F, OUTPUT);
pinMode(G, OUTPUT);
pinMode(DP, OUTPUT);

digitalWrite(DP ,HIGH);
}

void loop()
{
buttonUpState = digitalRead(switchUpPin);
buttonDownState = digitalRead(switchDownPin);

if (buttonUpState != lastButtonUpState)
{
if (buttonUpState == HIGH)
{
if(counter == 9)
{
counter = -1;
}
counter++;
Serial.println(counter);
changeNumber(counter);
delay(300);
}
else
{
Serial.println("OFF");
}
delay(50);
}
if (buttonDownState != lastButtonDownState)
{
if (buttonDownState == HIGH)
{
if(counter == 0)
{
counter = 10;
}
counter--;
Serial.println(counter);
changeNumber(counter);
delay(300);
}
else
{
Serial.println("OFF");
}
delay(50);
}
changeNumber(counter);
}
void changeNumber(int buttonPress)
{
switch (buttonPress)
{
//number 0
