Barcode hardware block
The Interstacks Barcode hardware block lets you connect a USB Barcode scanner to your stack. There are many vendors that sell Barcode scanners with a USB host connector (e.g. Sparkfun). Simply plug the Barcode scanner into the USB Host connector on the back of the Interstacks Barcode hardware block. When a barcode is scanned, its value will be output as a character string from the Barcode block, “Barcode”, output terminal. Use Stackbuilder to connect this output to the rest of your stack blueprint.
Connector on back is a USB Host connector
