Penampil Data

1. Menampilkan Counter 0 - 9 pada 7-segmen.

Gambar 1. Tampilan Counter 0-9 pada 7-segmen 1 digit

Kode Program:

1. int a = 0;
2. void setup() {
3.   for (int i = 0; i < 4; i++) {
4.     pinMode(i + 8, OUTPUT);
5.   }
6. }
7. void loop() {
8.   digitalWrite(8, bitRead(a, 0));
9.   digitalWrite(9, bitRead(a, 1));
10.   digitalWrite(10, bitRead(a, 2));
11.   digitalWrite(11, bitRead(a, 3));
12.   a++;
13.   if (a > 9) a = 0;
14.   delay(1000);
15. }

2. Membaca potensio dan menampilkan nilainya pada 7-segmen 4 digit.

Kode Program:

1. #include <SevSeg.h>
2. SevSeg sevseg;
3. void setup() {
4.   byte numDigits = 4;
5.   byte digitPins[] = {2, 3, 4, 5};
6.   byte segmentPins[] = {6, 7, 8, 9, 10, 11, 12, 13};
7.   bool resistorsOnSegments = false; // 'false' means resistors are on digit pins
8.   byte hardwareConfig = COMMON_ANODE; // See README.md for options
9.   bool updateWithDelays = false; // Default 'false' is Recommended
10.   bool leadingZeros = false; // Use 'true' if you'd like to keep the leading zeros
11.   bool disableDecPoint = true;
12.   sevseg.begin(hardwareConfig, numDigits, digitPins, segmentPins, resistorsOnSegments,
13.   updateWithDelays, leadingZeros, disableDecPoint);
14.   sevseg.setBrightness(90);
15.   Serial.begin(9600);
16. }
17. void loop() {
18.   static unsigned long timer = millis();
19.   if (millis() - timer >= 100) {
20.     timer = millis();
21.     int a = analogRead(A0);
22.     Serial.println(a);
23.     sevseg.setNumber(a);
24.   }
25.   sevseg.refreshDisplay(); // Must run repeatedly
26. }

3. Membaca potensio dan menampilkan nilainya pada LCD I2C.

Kode Program:

1. #include <LiquidCrystal_I2C.h>
2. LiquidCrystal_I2C lcd(0x27, 16, 2);
3. void setup() {
4.   Serial.begin(9600);
5.   lcd.init();
6.   lcd.clear();
7. }
8. void loop() {
9.   int a = analogRead(A0);
10.   Serial.println(a);
11.   lcd.print("          ");
12.   lcd.setCursor(0, 0);
13.   lcd.print(a);
14.   delay(100);
15. }

4. Membaca potensio dan menampilkan nilainya pada OLED I2C.

Kode Program:

1. #include <Wire.h>
2. #include <Adafruit_GFX.h>
3. #include <Adafruit_SSD1306.h>
4. #define SCREEN_WIDTH 128  // OLED display width, in pixels
5. #define SCREEN_HEIGHT 64  // OLED display height, in pixels
6. Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, -1);
7. void setup() {
8.   Serial.begin(9600);
9.   if (!display.begin(SSD1306_SWITCHCAPVCC, 0x3D)) {
10.     Serial.println(F("SSD1306 allocation failed"));
11.     for (;;)
12.       ;
13.   }
14.   display.setTextColor(WHITE);
15. }
16. void loop() {
17.   int a = analogRead(A0);
18.   Serial.println(a);
19.   display.clearDisplay();
20.   display.setTextSize(1);
21.   display.setCursor(0, 0);
22.   display.print("Nilai Potensio: ");
23.   display.setTextSize(2);
24.   display.setCursor(0, 10);
25.   display.print(a);
26.   display.display();
27.   delay(100);
28. }
