yes sir..i want to enable the signal if the password input by a keypad is valid....else it disable the signal...
here is my code in keypad:
#include <Password.h>
#include <LiquidCrystal.h>
#include <Keypad.h>
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
Password password = Password( "4567" );
const byte ROWS = 4; // Four rows
const byte COLS = 3; // Three columns
// 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] = {6, 7, 8, 9}; //connect to the row pinouts of the keypad
byte colPins[COLS] = {10, 13, 14}; //connect to the column pinouts of the keypad
// Create the Keypad
Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );
void setup(){
lcd.begin(16, 2);
keypad.addEventListener(keypadEvent); //add an event listener for this keypad
keypad.setDebounceTime(250);
}
void loop(){
char key = keypad.getKey();
if (key){
lcd.setCursor(0, 0);
lcd.print('*'); //display * when input the password
}}
//take care of some special events
void keypadEvent(KeypadEvent eKey){
switch (keypad.getState()){
case PRESSED:
switch (eKey){
case ' ': guessPassword(); break;
default:
password.append(eKey);
}
}}
void guessPassword(){
if (password.evaluate()){
delay(500);
lcd.setCursor(0, 1);
lcd.print("VALID PASSWORD"); //
password.reset(); //resets password after correct entry
delay(1000);
lcd.clear();
lcd.print("ACTIVATED!");
delay(2000);
lcd.clear();
}
else{
lcd.setCursor(0, 1);
lcd.print("INVALID PASSWORD");
password.reset(); //resets password after INCORRECT entry
delay(5000);
lcd.clear();
lcd.print("TRY AGAIN!");
delay(2000);
lcd.clear();
}
}
PIR Code + servo:
#include <Servo.h>
Servo myservo; // create servo object to control a servo
// a maximum of eight servo objects can be created
int pos = 0; // Variable to store the servo position in degrees
int pinPIRleft = 15; // left infrared sensor, digital pin
int pinPIRright = 16; // right sensor, digital pin
void setup() {
pinMode(pinPIRleft, INPUT); // set sensors as inputs
pinMode(pinPIRright, INPUT);
myservo.attach(17);
}
void loop(){
if (((pos < 180) && (digitalRead(pinPIRright) == HIGH)&& (digitalRead(pinPIRleft) == HIGH))){ //PIR detected motion
pos += 1; // increment servo degrees by +1
myservo.write(pos); // write the position to the servo
}
else {}// do nothing
if ((pos >= 1) && (digitalRead(pinPIRleft) == LOW) && (digitalRead(pinPIRright) == LOW)) { //no motion detected
pos -= 1;
myservo.write(pos);
}
else{}
}
Moderator edit: CODE TAGS AGAIN.
how can i combine the codes of keypad to PIR and servo..my project is when u input password then if it is valid..thats the time that the PIR will activate or on...else PIR will ignore signals...and when i enter again the password the PIR will off..
