Coding Arduino

Untuk coding arduino nya. Project ini terdiri dari dua bagian coding. 

Yaitu bagian coding servo dan juga bagian coding sensor ultrasonic nya. 

Untuk coding tes servo nya kalian bisa lihat disini :

#include <Servo.h> Servo myservo; // create servo object to control a servo // twelve servo objects can be created on most boards int pos = 0; // variable to store the servo position void setup() { myservo.attach(9); // attaches the servo on pin 9 to the servo object } void loop() { for (pos = 0; pos <= 180; pos += 1) { // goes from 0 degrees to 180 degrees // in steps of 1 degree myservo.write(pos); // tell servo to go to position in variable 'pos' delay(15); // waits 15ms for the servo to reach the position } for (pos = 180; pos >= 0; pos -= 1) { // goes from 180 degrees to 0 degrees myservo.write(pos); // tell servo to go to position in variable 'pos' delay(15); // waits 15ms for the servo to reach the position } }Serial.println("cm"); }

Coding Sensor

#include <NewPing.h> #define TRIGGER_PIN 3 // Arduino pin tied to trigger pin on the ultrasonic sensor. #define ECHO_PIN 4 // Arduino pin tied to echo pin on the ultrasonic sensor. #define MAX_DISTANCE 200 // Maximum distance we want to ping for (in centimeters). Maximum sensor distance is rated at 400-500cm. NewPing sonar(TRIGGER_PIN, ECHO_PIN, MAX_DISTANCE); // NewPing setup of pins and maximum distance. void setup() { Serial.begin(115200); // Open serial monitor at 115200 baud to see ping results. } void loop() { delay(50); // Wait 50ms between pings (about 20 pings/sec). 29ms should be the shortest delay between pings. Serial.print("Ping: "); Serial.print(sonar.ping_cm()); // Send ping, get distance in cm and print result (0 = outside set distance range) Serial.println("cm"); }
