But, after reading through the documentation, I do not see a way for an Arduino to accept commands from a computer in real time and act on them. Is there a way, to "analogwrite(getusbdata)" of some sort?
It communicates on digital pins 0 (RX) and 1 (TX) as well as with the computer via USB. Thus, if you use these functions, you cannot also use pins 0 and 1 for digital input or output.Source: http://arduino.cc/en/Reference/Serial
The USB B plug, or Pins 0 and 1?
but I CAN program the nano using USB,
And when I just directly connect the Arduino to the computer via a USB cable, I can control and receive data using Processing
When I say Serial.Begin(9600) for example, which one will it use? The USB B plug, or Pins 0 and 1? Or both simultaneously? So I must use the software serial library or something.
And when I just directly connect the Arduino to the computer via a USB cable, I can control and receive data using Processing?
try sending a signal through the serial pins for 30 meters. Of the signal arrives fine, great, i'll leave it at that.
Am I correct if I say that the Bootstrap pins may be left alone
as the chip itself has an internal capacitor?
