Here is the code:
#include <LiquidCrystal.h> // include the LCD library
LiquidCrystal lcd( 8, 9, 4, 5, 6, 7 );
int VinPin = A5; //Voltage input pin
int VinValue1 = 0;
int VinValue2 = 0;
int TimeValue1 = 0;
#define NUM_SAMPLES 10
int sum = 0; // sum of samples taken
unsigned char sample_count = 0; // current sample number
float voltage = 0.0; // calculated voltage
void setup() {
lcd.begin(16, 2); // lcd rows and columns
lcd.print("Volts % Hours"); // title of sorts
}
void loop() {
while (sample_count < NUM_SAMPLES) {
sum += analogRead(A5);
sample_count++;
delay(10);
}
voltage = ((float)sum / (float)NUM_SAMPLES * 5.015) / 1024.0;
VinValue1 = analogRead(VinPin) / 10;
VinValue2 = VinValue1 / 1.02;
lcd.setCursor(0, 1);
lcd.print(voltage);
lcd.setCursor(7, 1);
lcd.print(VinValue2);
delay(100);
lcd.setCursor(13, 1);
TimeValue1 = VinValue2 / 12;
lcd.print(TimeValue1);
sample_count = 0;
sum = 0;
delay(1);
}
