Send data to usb port i want to send data from my HTC Incredible S to my Arduino Uno. I want to do this by using the micr usb port.
But it seems like my smartphone is not supporting the usb host mode.
Will it still be possible to send data by usb? And if yes, how?
This question is probably off topic as some programming is involved. Look at Android USB Accessory Mode if you are trying to connect an Arduino with Android.
