A standard usb plug has four pins. i am just trying to find out what these pins mean.
i found this site here (http://pinouts.ru/Slots/USB_pinout.shtml
) which describes the as VCC, GND, D+ and D-
can someone tell me if D+ and D- are the same as Rx and Tx pins?
i have found a bluetooth device with a USB plug on the end (http://www.zenocom.co.kr/new/eng/products/sub01_02.html
), and am wondering if i can just pull this off and plug into pwr, gnd, rx and tx pins on arduino.
