To get this working, you will need the USB Host Shield for the Arduino and a Bluetooth dongle. Currently the buttons and joysticks work, and support for the light sensor, rumble, and touchpad is on the way. The library makes it easy to read most of the inputs from the controller. But using that driver is much more complex than just using the internal serial interface.Looking to interface your Arduino with the PS4 controller? has updated his USB host library with support for the controller. If you insist in using the USB Host Shield you need the FTDI driver. Can you check that by a multimeter? As these signals most probably is routed to the bottom layer and back you have a good chance to get that signal to connect it to the controlling Arduino. Although it's not clearly visible on the datasheet picture I guess the FTDI serial interface (pins 1 and 5) is directly connected to the hardware serial interface of the ATmega (pins 30 and 31). The board you bought contains an ATMega168 (the processor the first Arduino had) and an FTDI232 which converts the TTL UART to USB. Any links or advice would be appreciated, thank you! It seems I might need some sort of driver from what I understand, but I'm not sure what that means or how to connect that sort of info. I see in the documentation for the RFID reader I bought, there's some serial commands I can do to read from the animal tag (page 13 ) but I'm struggling to understand how to call these from my arduino code to print the RFID tag it reads in the serial monitor. (the GitHub - felis/USB_Host_Shield_2.0: Revision 2.0 of USB Host Library for Arduino.) I'm using USB_Host_Shield_2.0 library to read data from the USB. I bought this RFID reader: FDX-B/HDX RFID Reader Writer with external antenna and USB port - $47.00 : Zen Cart!, The Art of E-commerceĪfter my learning curve, I realized I should have bought one with TTL connection and not USB, but since it took awhile to get here, instead I bought a USB host shield to connect to my Arduino Uno R3.

I am trying to use an RFID reader to send data to an arduino (trying to build a homemade cat feeder with two hungry cats who eat each others food) to control an entry passageway. I apologize, as I'm fairly new to this sort of stuff and trying my best to learn my way through this.
