Arduino for ODROID-GO - Ultrasonic Distance Meter

You can have a portable Ultrasonic distance meter in your hand.

Make sure that you have these products:

  • An Ultrasonic Sensor
  • Jumper cables and a bread board
  • An auxiliary battery if using it portable
    • This module requires 5V input power, but ODROID-GO outputs 3V3 for the power pin(#6) on its header pins. Thus, it is required to use the 5V USB VBUS pin(#10) with an external USB power source.
    • Alternatively, you can use a Step-up DC-DC converter and a level shifter.
  • A MicroUSB cable

Set up the development environment for Arduino on your system.

Please refer to the picture below when you set up your hardware.
We use the parts below:

  • Ultrasonic sensor: HC-SR04
  • Step-up DC-DC 3V3 to 12V(set to 5V for now) converter: MT3608
  • Logic level converter: BSS138

Click the Files → Examples → ODROID-GO → Applications → Ultrasonic_Distance_Meter menu to import and press CTRL-U to compile/upload.

Uploading is complete when the message “Hard resetting via RTS pin…” is seen.

After the upload completes, ODROID-GO reboots automatically.

The screen shows a measured distance in inch, cm units when an obstacle is detected at the front of the Ultrasonic sensor.
If the measurement conditions are not met, such as a distance that is too far or too short, the result text on the screen will be colored red.
If it measures normally, the text will be colored green.
