Alat Kendali Dimmer dan Timer Interface LCD TFT

Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang menggunakan dimmer modul dan timer sebagi fitur utamanya. interface menggunakan LCD TFT dan terdapat pula fitur EEprom sehingga data tidak hilang ketika di simpan. untuk lebih jelasnya berikut adalah koding dan komponennya.

Monitoring Timbangan Berat dan Tinggi Badan 4 LoadCell Arduino

Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat mengukur tinggi dan berat badan menggunakan 4 buah loadcell dan amplifier modul HX711 dengan Arduino uno. untuk sensor jarak yang dipakai bisa menggunakan HC-SRF04. untuk lebih jelasnya berikut adalah kodingdan skemanya.

1. Skema 4 Loadcell

2. Program Arduino IDE

#include <Wire.h>
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27, 16, 2);
#include "HX711.h"

// HX711.DOUT - pin #9
// HX711.PD_SCK - pin #8

#define trigPin 7
#define echoPin 6

int counter = 0; //Variabel penghitung nilai
int aState; //Variabel kondisi
int aLastState; //Variabel kondisi terakhir

HX711 scale(9, 8);

long duration, distance;
float tera = 0;
int berat;
float fix;
int x;
int jarak;
int sp = 30;
int tinggi;

void setup() {

Serial.begin(9600);
lcd.begin();
lcd.clear();
lcd.noCursor();

pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);

scale.set_scale(2280.f); // this value is obtained by calibrating the scale with known weights; see the README for details
scale.tare(); // reset the scale to 0

lcd.setCursor (0,0);
lcd.print ("LOADING... ");
delay(5000);
lcd.clear();
}

void loop() {

digitalWrite(trigPin, LOW); // Added this line
delayMicroseconds(2); // Added this line
digitalWrite(trigPin, HIGH);
delayMicroseconds(10); // Added this line
digitalWrite(trigPin, LOW);
duration = pulseIn(echoPin, HIGH);
distance = (duration/2) / 29.1;
jarak = 200 - distance;

berat = scale.get_units(10) * -1;
fix = (berat - 2.1036)/8.978;

if(fix < 0){
fix = 0;
}

lcd.setCursor (0,0);
lcd.print ("W/H= ");
lcd.print (fix);
lcd.print (" / ");
lcd.print (jarak);
lcd.print (" ");

Serial.print(berat);
Serial.print(",");
Serial.println(jarak);

scale.power_down();
delay(100);
scale.power_up();

if (Serial.available() > 0) {
String teststr = Serial.readString();
lcd.setCursor(0,1);
lcd.print(teststr);
}
}
