my first sketch
is
#include <DS3231.h>
#include <Servo.h>
#include <LiquidCrystal.h>
#include <Keypad.h>
#include <SoftwareSerial.h>
const byte ROWS = 4; // Four rows
const byte COLS = 4; // Three
// Define the Keymap
char keys[ROWS][COLS] = {
{'1','2','3'},
{'4','5','6'},
{'7','8','9'},
{'*','0','#'}
};
// Connect keypad ROW0, ROW1, ROW2 and ROW3 to these Arduino pins.
byte rowPins[ROWS] = { 0, 2, 3, 4 };
// Connect keypad COL0, COL1 and COL2 to these Arduino pins.
byte colPins[COLS] = { 5, 6, 7 };
// Create the Keypad
Keypad kpd = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );
DS3231 rtc(A4, A5);
Servo servo_test; //initialize a servo object for the connected servo
LiquidCrystal lcd(A0, A1, A2, 8, 12, 13); // Creates an LC object. Parameters: (rs, enable, d4, d5, d6, d7)
//int angle = 0;
// int potentio = A0; // initialize the A0analog pin for potentiometer
int t1, t2, t3, t4, t5, t6;
boolean feed = true; // condition for alarm
char key;
int r[6];
void setup()
{
servo_test.attach(9); // attach the signal pin of servo to pin9 of arduino
rtc.begin();
lcd.begin(16,2);
servo_test.write(55);
Serial.begin(9600);
pinMode(A0, OUTPUT);
pinMode(A1, OUTPUT);
pinMode(A2, OUTPUT);
}
void loop()
{
lcd.setCursor(0,0);
int buttonPress;
buttonPress = digitalRead(A3);
if (buttonPress==1)
setFeedingTime();
//Serial.println(buttonPress);
lcd.print("Time: ");
String t = "";
t = rtc.getTimeStr();
t1 = t.charAt(0)-48;
t2 = t.charAt(1)-48;
t3 = t.charAt(3)-48;
t4 = t.charAt(4)-48;
t5 = t.charAt(6)-48;
t6 = t.charAt(7)-48;
lcd.print(rtc.getTimeStr());
lcd.setCursor(0,1);
lcd.print("Date: ");
lcd.print(rtc.getDateStr());
if (t1==r[0] && t2==r[1] && t3==r[2] && t4==r[3]&& t5<1 && t6<3 && feed==true)
{
servo_test.write(220); //command to rotate the servo to the specified angle
delay(8000);
servo_test.write(75);
feed=false;
}
}
void setFeedingTime()
{
feed = true;
int i=0;
lcd.clear();
lcd.setCursor(0,0);
lcd.print("Set feeding Time");
lcd.clear();
lcd.print("HH:MM");
lcd.setCursor(0,1);
while(1){
key = kpd.getKey();
char j;
if(key!=NO_KEY){
lcd.setCursor(j,1);
lcd.print(key);
r = key-48;
- i++;*
- j++;*
- if (j==2)*
- {*
- lcd.print(":"); j++;*
- }*
- delay(500);*
- }*
- if (key == '#')*
- {key=0; break; }*
- }*
}
and my second scetch is
#include <SoftwareSerial.h> // TX RX software library for bluetooth
#include <Servo.h> // servo library
Servo myservo; // servo name
int bluetoothTx = 10; // bluetooth tx to 10 pin
int bluetoothRx = 11; // bluetooth rx to 11 pin
SoftwareSerial bluetooth(bluetoothTx, bluetoothRx);
void setup()
{ - myservo.attach(9); // attach servo signal wire to pin 9*
- //Setup usb serial connection to computer*
- Serial.begin(9600);*
//Setup Bluetooth serial connection to android - bluetooth.begin(9600);*
}
void loop()
{ - //Read from bluetooth and write to usb serial*
- if(bluetooth.available()> 0 ) // receive number from bluetooth*
- {*
- int servopos = bluetooth.read(); // save the received number to servopos*
- Serial.println(servopos); // serial print servopos current number received from bluetooth*
- myservo.write(servopos); // roate the servo the angle received from the android app*
- }*
}
