The Ark by Dave's Hack ShackInventory Project using an MKR1010, MKR MEM Shield configured with an Access Point Web Interface and USB Barcode Scanner
Basic Operation
Read moreI created a YouTube video that provides additional details and a demonstration, the Link is: The Ark Video
The Ark uses 4 key components an Arduino MKR1010 controller, Arduino MKR MEM Shield (with 16GB SD card formatted as FAT32), BT 2D Barcode Scanner and a Micro Type B to USB Female Hub cable. A prototype was constructed:
Prototype
I plan on encasing the prototype in a project box for production use.
Barcode Scanner
Power on The Ark (if the /ARK directory is not found it will create it automatically)
Connect to the Access Point (you will get served a Web Page Interface)
Enter a Project Name (this will create a project with the name entered if it does not exist)
Start scanner barcodes (That's It!)Project Operations
Change - Create/Change the Active Project using the name provided
Show Projects - list all projects in the /ARK directory
Show Project - show all scanner barcodes
Remove Directory - Remove the /ARK directory (not recommend)
Remove Project - Delete an Active Project
Clear Project - empty the contents of a project
Download Project - Transfer the contents of the Project Responses area to the attached device
Project Mode - switch between the Create Project (manage projects) and Display Project (search for a barcode) modesProject Notes
The Barcode Scanner can be recharged from The ARK by removing the USB dongle and attaching it to the ARK via the USB cable it comes with
The Ark has a power monitor circuit with a low voltage threshold set to 10.50v, once reached the attached device will beep and the voltage display will turn RED
The WEB page is HTML and javascript, it is gzipped and base 64 encoded to save code space
On startup if Green LED stay lit we did not find the WiFi module
On startup if Green LED is flashing every 100ms the Access Point did not start
On startup if Green LED is flashing every 1000ms the SD Card did not startArduino Software Notes
Libraries needed : <SPI.h>, <SD.h>, <global.h>, <base64.h>, <WebSocketClient.h>, <WebSocketServer.h>, <WiFiNINA_Generic.h> and <KeyboardController.h>
