Mini Radar Arduino Menggunakan Ultrasonic by Processing

Dalam Tutorial Arduino ini, saya akan menunjukkan bagaimana Anda bisa membuat radar yang keren ini dengan menggunakan  Arduino dan Processing.

Dan untuk bisa menampilkan Radar pada Monitor PC kita tidak hanya menggunakan Arduino IDE namun kita masih membutuhkan aplikasi lain yaitu Processing IDE.

langak-langkah yang harus dilakukan adalah:

1. Install Arduino IDE dan Processing IDE
2. Upload Source Code untuk Arduino
