aRduinoScope

A poor-man's oscilloscope using an Arduino and Ruby

This project works as a very low resolution oscilloscope.

Screen Shot

Pros

  • Cheap! $20 for an extra Arduino and you're up and running.
  • Easily test output from analog sensors.
  • Monitor all analog ports.

Cons

  • Low resolution.
  • Low voltage - Do not supply more then 5 volts to the arduino.

Using aRduinoScope

The Arduino

  1. Use the Arduino IDE to install the StandardFirmata example onto the arduino.
  2. Connect a wire to A0 on the Arduino, and any other analog inputs you plan to use.
  3. Connect the wires to any sensors or outputs being tested.

WARNING

Do NOT connect more then 5 volts directly to any of the arduino inputs.

Key bindings

  • 0, 1-5 - Enable or disable graph display of analog input
  • P - Pause display
  • ESC - Quit

Install

  1. Install required libs
  1. Run project ruby oscilloscope.rb
  2. run gem install oscilloscope
  3. run oscilloscope
