Modul 2: Tugas Pendahuluan 1

 

PERCOBAAN 4 KONDISI 4

1. Kondisi [Kembali]

     Keypad 1 hingga 9 memberikan PWM 255-0 dengan jarak PWM antar Key 28

2. Rangkaian Simulasi [Kembali]




Listning Program:
#include <Servo.h>
#include <Keypad.h>

Servo servoMotor;
const int servoPin = 11; // PWM pin for servo
const int numRows = 4;  // Number of rows in keypad
const int numCols = 3;  // Number of columns in keypad
char keys[numRows][numCols] = {
  {'1', '2', '3'},
  {'4', '5', '6'},
  {'7', '8', '9'},
  {'*', '0', '#'}
};
byte rowPins[numRows] = {9, 8, 7, 6}; // Rows 0 to 3
byte colPins[numCols] = {5, 4, 3};     // Columns 0 to 2
Keypad keypad = Keypad(makeKeymap(keys), rowPins, colPins, numRows, numCols);

// Function to map keypad values to PWM values
int mapKeypadToPWM(char key) {
  // Convert the character to integer
  int value = key - '0';
 
  // Calculate PWM value with a gap of 28 between keys
  int pwmValue = 255 - (value * 28);
 
  // Ensure PWM value stays within 0 to 255 range
  pwmValue = max(0, min(255, pwmValue));
 
  return pwmValue;
}

void setup() {
  servoMotor.attach(servoPin);
  servoMotor.write(90); // Initial position
  Serial.begin(9600);
}
 
void loop() {
  char key = keypad.getKey();
   
  if (key != NO_KEY) {
    Serial.println(key);
     
    // Perform actions based on the key pressed
    switch (key) {
      case '1':
        // Set PWM value to 255
        servoMotor.write(mapKeypadToPWM(key));
        break;
      case '2':
        // Set PWM value to 227
        servoMotor.write(mapKeypadToPWM(key));
        break;
      case '3':
        // Set PWM value to 199
        servoMotor.write(mapKeypadToPWM(key));
        break;
      case '4':
        // Set PWM value to 171
        servoMotor.write(mapKeypadToPWM(key));
        break;
      case '5':
        // Set PWM value to 143
        servoMotor.write(mapKeypadToPWM(key));
        break;
      case '6':
        // Set PWM value to 115
        servoMotor.write(mapKeypadToPWM(key));
        break;
      case '7':
        // Set PWM value to 87
        servoMotor.write(mapKeypadToPWM(key));
        break;
      case '8':
        // Set PWM value to 59
        servoMotor.write(mapKeypadToPWM(key));
        break;
      case '9':
        // Set PWM value to 31
        servoMotor.write(mapKeypadToPWM(key));
        break;
      default:
        break;
    }
  }
}

4. Prinsip Kerja [Kembali]

    Pada kondisi yang diminta, yaitu simulasi rangkaian yang melibatkan komponen , keypad dan PWM dimana merupakan implementasi penggunaan PWM dengan input keypad. Ketika masing masing tombol keyped ditekan dari 0-9 maka PWM akan bergerak dengan kondisi memberikan PWM 255-0 dengan jarak PWM antar Key 28
