ArduScope

Usage

Open up the client application

Getting started

If you are in a possession of an Arduino Uno board, you should be able to start analysing signals in just a few minutes by following this guide.

1. Burn the Arduscope firmware to your Arudino Uno board.

2. Install Arduino Create Agent. A piece of software that handles the serial communication between the Arduino board and the Arduscope web interface. Github sources here.

3. Configure Arduino Create Agent to accept requests from Arduscope web interface. You will have to find the installation folder for arduino-create-agent. The location of this folder depends on your operating system:

   • MacOS: /Users/[your-username]/Applications/ArduinoCreateAgent/ArduinoCreateAgent.app/Contents/MacOS/Arduino_Create_Agent

   Under this folder you should see a config.ini file that is the main configuration file used by the Arduino Web IDE.
   To make the Arduino Agent accept connection from our web interface, create a new configuration file arduscope.ini, and paste the following lines:

   gc = std
   name = arduscope
   origins = https://petrica.github.io
   crashreport = true

   This will enable CORS for the URL https://petrica.github.io, where the Arduscope web interface sits.

   • Restart Arduino Agent. You should find the agent in your tray bar.
   • From the dropdown menu select our new configuration profile:
     

4. Access the Arduscope web interface and connect your Arduino Uno to the USB. You should see the USB port displayed in the Arduscope web interface. Click Connect and once successful the Sample Rate dropdown should be populated with the sampling frequencies that the Arduscope is capable of handling.
   

5. Connect pin A0 to pin 11 on the Arduino board and click Acquire on the Arduscope web interface. You should see the 500Hz calibration signal displayed.
