QUADCOPTER
UNTUK SISTEM PEMANTAU
UDARA BERBASIS MIKROKONTROLLER ATMEGA 328
ABSTRAK
Telah dirancang sebuah sistem pemantau udara (quadcopter) untuk pemantau yang dapat mengendalikan objek terbang di udara. Sistem quadcopter tersebut memiliki ukuran 30 cm x 30 cm terdiri dari empat buah baling baling (panjang 20.32 cm). Dalam menjaga keseimbangan quadcopter selama bermanufare di udara, digunakan sensor accelerometer MMA7260Q. Remote control memberikan perintah dan ditangkap receiver pada quadcopter, perintah atau data yang diterima oleh receiver diproses oleh mikrokontroller ATmega 328. ATmega 328 membaca data yang diberikan dan memberikan sinyal pada setiap komponen untuk melaksanakan perintah. Quadcopter menggunakan cctv wireless yang dapat merekam objek dan dilengkapi dengan sistem pengiriman dengan pemancar Rf433. Kemudian data yang dikirim ditangkap oleh receiver pada PC. Untuk menghubungkan antara penerima (receiver) dengan Personal Computer (PC) dibutuhkan converter, hal ini dibutuhkan karena pada Personal Computer (PC) tidak mempunyai konektor AV (audio video), oleh sebab itu dibutuhkan easy capture . Dari hasil pengujian motor, quadcopter mendapatkan respon untuk terangkat dimulai dari pulsa 77 dengan rata-rata nilai Revolution Per Minute (RPM) 122.75 dan rata-rata Pulse Width Modulation (PWM) 13.47 Hz. Dari hasil pengujian kemiringan dapat diketahui bahwa kemiringan tergantung posisi quadcopter.
Kata Kunci : Quadcopter, Sensor accelerometer MMA7260Q, Mikrokontroller ATmega 328, PC, baling-baling.

DESIGNING OF QUADCOPTER FOR AIR MONITORING
SYSTEM BASED WITH ATMEGA 328 MICROCONTROLLER
ABSTRACT
An air monitoring system (quadcopter) that have purposed to monitoring which can control flying object through the air, have been designed. The quadcopter system has a size of 30 cm x 30 cm which consists of four propellers (have length 20.32 cm). To maintaining of quadcopter during manufaring in the air, used MMA7260Q accelerometer sensor. The remote control gives a command and the receiver,it processed by the Atmega 328 microcontroller. The Atmega 328 microcontroller will read input data and signals on every component to execute the command. Quadcopter using wireless cctv to recorded the object and was equipped by a delivery system with RF433 transmitter. Then, data which have been sent, is capture by receiver on PC. To connected the receiver with PC needed a converter , it is needed because PC does not have AV connector (audio video), so that, it would takes the easy capture. From the resulted and analyzed testing of the motor, show that quadcopter response to elevated at pulse which started from 77 with have an average value of Revolution Per Minute (RPM) is 122.7 and average value of Pulse Width Modulation (PWM) is 13.47 Hz. From the resulted of slope testing, it was knew that the slope was depended by quadcopter position.
