A aruino based radar syster for fun

Throughout the media we see cars and robots using expensive laser-based sensor to map the environment, we then tried to roll-out our own version with items that are common to any maker's toolbox.

• Sample output, scanned my room. *

• Hardware
  • Arduino UNO ( or compatible )
  • 2 Micro servo motors
  • A ultrassonic distance sensor
  • Jumpers, about 16 of them.
  • Protoboard
  • USB Cable
  • A Laptop
• Software
  • Processing 3+
  • Arduino IDE

1. Plug in the arduino in the computer.
2. Program the arduino with the code in range-radar.ino
3. Open up this processing sketch.
4. Hit "run" and watch as the picture is formed

If you so desire, you can change the resolution by altering some variables to the same value in both range-radar.ino and the processing sketch. In the sketch, the variable is called stepAngle, in range-radar.ino, it's called step.

If you do not have permission to read/write to the serial port, be sure to change it's ownership. For this, you can use the following command:

> sudo chown <your username> /dev/tty<nameOfSerial>

Usually, the serial name is something along the lines of "USB0", "SO0". Also, the file that represents the serial communication only appears when you connect the arduino.
