Pada siang hari ini saya akan menjelaskan project ketiga saya menggunakan Leap Motion, kali ini alat yang dibuat adalah alat untuk kendali angle servo, jadi servo akan bergerak sesuai arah / posisi tangan berada, untuk aplikasinya sangat banyak sekali seperti halnya kendali robot lengan menggunakan tangan, kendali buka-tutup pintu dengan gesture tangan, dan lain sebagainya, komponen yang dibutuhkan tidaklah banyak yaitu Arduino Uno, Servo, dan Leap Motion. Untuk lebih jelasnya berikut adalah skema dan programnya.
a. Arduino Uno
b. Leap Motion
c. Motor Servo
d. Program Arduino IDE
#include <LiquidCrystal.h>
#include <Servo.h>
int currentRead;
Servo myservo;
LiquidCrystal lcd(8, 9, 10, 11, 12, 7);
void setup() {
myservo.attach(6);
Serial.begin(9600);
lcd.begin(16, 2);
lcd.clear();
lcd.noCursor();
}
void loop() {
if (Serial.available()) {
currentRead = Serial.read();
if (currentRead < 50)
{
currentRead = 50;
}
if (currentRead > 200)
{
currentRead = 200;
}
lcd.setCursor(0, 0);
lcd.print("Angle X = ");
lcd.print(currentRead);
myservo.write(currentRead);
delay(200);
lcd.clear();
}
#include <Servo.h>
int currentRead;
Servo myservo;
LiquidCrystal lcd(8, 9, 10, 11, 12, 7);
void setup() {
myservo.attach(6);
Serial.begin(9600);
lcd.begin(16, 2);
lcd.clear();
lcd.noCursor();
}
void loop() {
if (Serial.available()) {
currentRead = Serial.read();
if (currentRead < 50)
{
currentRead = 50;
}
if (currentRead > 200)
{
currentRead = 200;
}
lcd.setCursor(0, 0);
lcd.print("Angle X = ");
lcd.print(currentRead);
myservo.write(currentRead);
delay(200);
lcd.clear();
}
}

f. Cara Install Library
1. Buka Software Processing lalu Pilih Sketch -> Import Library -> add library
2. Search "leapmotion" lalu Pilih seperti di gambar berikut dan INSTALL
3. Library Siap digunakan
