ARDUINO PARSING DATA UART SERIAL alat Monitor Kelembaban Tanah / Soil Moisture dan Potensio Slider WIRELESS HC-12 INTERFACE DELPHI 7

ARDUINO PARSING DATA UART SERIAL alat Monitor Kelembaban Tanah / Soil Moisture dan Potensio Slider WIRELESS HC-12 INTERFACE DELPHI 7  

            Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang berfungsi untuk memonitor tegangan dari potensio slider dan kelembaban tanah / soil moisture dengan menggunakan Arduino. alat ini terdapat bagian master dan bagian slave jadi butuh 2 arduino sebagai master dan slave. komunikasi master - slave menggunakan wireless modul HC-12 dan menggunakan parsing data serial uart untuk memilah dua data yang dikirim oleh master kepada slave. untuk lebih jelasnya berikut adalah komponen dan programnya.

a. Arduino Uno

b. Sensor Kelembaban Tanah / Soil Moisture

c. Potensio Slider

d. Modul Wireless HC-12

e. LCD 20x4 + I2C

f. Program Arduino IDE Master

#include <Wire.h>

int dataadc1;
int dataadc2;
int maxval = 1023;
int minval = 0;
int minvalx = 0;
int maxvalx = 100;
int rawValue;

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

void loop() {

  dataadc1 = analogRead(A0);
  dataadc2 = analogRead(A1);

int panjang = map(dataadc2, maxval, minval, minvalx, maxvalx);

//secara wireless
Serial.print("*");
Serial.print(dataadc1);
Serial.print(",");
Serial.print(panjang);
Serial.println("#");

//pakai kabel   
//Serial.print(dataadc1);
//Serial.print("\n");
//Serial.print(panjang);
//Serial.print("\n");

delay(1000);
}
