Boncuk New Member Oct 30, 2008 #2 The outer pins of the USB connector are supply voltage. Pin1=+5VDC, pin2=data-, pin3=data+, pin4=ground. Connect the load only to the outer pins. Use a 180Ω current limiting resistor for the LED. Boncuk Attachments usb_a_b_male.gif 933 bytes · Views: 453

A alwindawee New Member Oct 30, 2008 #3 thanx to your reply, but I want to be able to turn on and turn off the LED through a programe that written in vb6. I mean "controlling the USB port". thanx again.

3v0 Coop Build Coordinator Forum Supporter Oct 30, 2008 #5 Look at the USB Wacker link in my signature. The example code uses Liberty Basic instead of VB but it should be easy to translate. EDIT: That link seems to be down just now. Sparkfun sells one. Last edited: Oct 30, 2008

blueroomelectronics Well-Known Member Oct 30, 2008 #9 Nope all FT232 IC are surface mount. I'd use a 18F2550 and bitwhacker or Swordfish full edition (supports USB)
