A multifunction I/O device built atop the ATmega328P microprocessor.

• Setup
  • Step 1 - Install arduino-cli
  • Step 2 - Install package
  • Step 3 - Upload source
  • Step 4 - Start webserver
• Usage
  • Window: Digital
  • Window: PWM
  • Window: AnalogRead
  • Window: DigitalRead

This project uses arduino-cli to upload Arduino source code to the target device. To install arduino-cli, follow the Quickstart section provided by the arduino-cli developers. NOTE: This project was only tested with the Arduino Uno. Other boards may or may not be compatible.

To install the inodaqv2 Python package, run:

make setup

The installation process will produce some build artifacts. These artifacts can be cleaned up by running:

make clean

To upload the source, run:

./upload

Which will prompt:

...
1. Select serial port for upload [default = COM3]:
>

Where this port would refer to a valid serial device, such as COM3 on Windows or /dev/ttyS2 on Linux. Hit enter and continue. The install script will then prompt:

...
2. Select Fully Qualified Board Name (FQBN) [default = arduino:avr:uno]:
>

Insert a valid FQBN and hit enter.

As a final sanity check, run the webserver:

inodaq --serial-port=<serial-port>

This command will host a site locally using Flask's internal development server. Note that this webserver should not be used in a production environment. A URL will be printed to the console if a connection to the serial device is successfully established. Navigate to this URL to use the product.

This window is used to toggle digital pins 2 through 13 on the device. The pins toggle to either a HIGH or LOW state. Toggling pin 13 on an Uno device should turn the onboard LED either on or off. This behaviour can be used as a sanity check.

This window can be used to emit a PWM wave on any PWM compatible digital pin. The slider is used to select the duty cycle of the emitted wave. The PWM output frequency is approximately 490 Hz.

This window can be used to read the analog voltages on analog pins A0 through A5.

This window can be used to read the binary states of analog pins A0 through A5.
