Monitoring Tegangan Dengan Arduino dan Interface DELPHI 7

Monitoring Tegangan Dengan Arduino dan Interface DELPHI 7

             Pada kesempatan emas ini saya akan menjelaskan mengenai bagaimana cara membuat interface Delphi 7 dari mikrokontroller Arduino, jadi prinsip kerjanya begini, Arduino mengirimkan data berupa data adc, yang berjumlah 2 buah yaitu adc A dan adc B. kemudian didalam delphi ada dua buah program yaitu menampilkan kedua data tersebut kedalam satu grafik dan yang kedua yaitu menampilkan kedua data tersebut ke grafik yang terpisah atau sendiri-sendiri. yang harus diperhatikan yaitu pertama install dulu comport untuk delphinya, disini saya menggunakan cport 3.10. untuk lebih jelasnya berikut program dan skemanya.

a. Arduino Uno

b. Program Arduino

// the setup routine runs once when you press reset:
void setup() {
  // initialize serial communication at 9600 bits per second:
  Serial.begin(9600);
}

// the loop routine runs over and over again forever:
void loop() {
  // read the input on analog pin 0:
  float sensorValue = analogRead(A0);
  float sensorValue1 = analogRead(A1);
 
  // print out the value you read:
  Serial.print(sensorValue),Serial.println ('a');
  Serial.print(sensorValue1),Serial.println ('b');
 
  delay(50);        // delay in between reads for stability
}

e. Cara Penggunaan Alat

            Untuk menggunakan alat ini yaitu pertama download / upload program Arduino terlebih dahulu, kemudian pastikan Arduino mengirimkan data secara serial dengan menggunakan fitur serial monitor pada software Arduino. jika semua berhasil maka buat interface Delphi 7 dan pastikan tidak error saat RUN. langkah terakhir yaitu lihat COM port pada Arduino lalu pilih COM tersebut. jika berhasil maka tampilan grafik akan muncul pada interface Delphi 7. jika mau download program diatas bisa melalui link dibawah ini.
