Arduino + QR Code reader + USB Key

Using Arduino Project Guidance
1

Hello,

I'm electronics engineer but totally newbie in Arduino. All my previous projects was custom board with MCU and programmed in C language.

So I would like to test Arduino with peripheral in USB (USB Key and QR code reader) and another secondary peripherals like UART, IO and I2C to win time on POC developement soI have several questions:

  • Is it complicated to use the USB port in Arduino ? are there available libraries to use it ?
  • Which kind of Arduino model can I use ? is there some model with 2 USB ports ?

Best Regards,

The Arduino USB port is a client for connecting to Pc.
To read USB from periferal devices You need a USB host shield.

The Leonardo has native USB capability but I have no experience using it so cannot offer advice.

This will be a job for a Raspberry Pi. :face_with_raised_eyebrow:

Not an Arduino.

Hi, thanks a lot for your advices. I will see about Leonardo and raspberry solution.

Thanks,

As a "device". Don't know about it operating as a "host". :thinking: It appears not.
