May be but I'd sort out the PID first. The accel/gyro could be thrown by currents long term maybe look at adding a compass and see if you get it to steer a pre programmed course. Or even a GPS!.

But do one thing at a time.

Take a look at the rest of the thread you took this from they won't be change by you starting a new topic.

Your not sending '\n' so nothing is printed or at least it is not there when to try to read it.

No. That's why you need the switch.

There is nothing to do!. The chip on that shield will talk to anything via I2C.

Take a look at PID http://en.wikipedia.org/wiki/PID_controller There is an arduino lib for it look in the playground/examples areas of the web site.

Both the Micro and the Leonardo have HOST ports.
No the Leo and micro do NOT have USB host ports but they do have a much more versatile USB (it can be used as a number of different types of USB slave).

The YUN however really does have a USB Host port.

Also, there's bunch of stuff going on  , like recieving date from an acclerometer, printing to the serial monitor lighting an led.

Any and all of the above may mess up your "tempo" , so post your code!

So Serial print the values from analogRead and map what are they? By the way what external hardware are you using.

You may need to give the XBee time to sort its self out Try a 30 second delay in setup()

See blink without delay and the look up Finite Sate Machines (FSM) in the playground/examples.

I expect to click links not select, copy, pate edit and click.

Motor Control Pin Jumper
Applying the Motor Control Pin Jumpers will allocate Pin 5,6,7,8 for motor control.
Removing the jumpers will release the above Pins.

One things for sure the software's ok. We I think it a hardware setup problem.

@ electricmotorcycles - You should have read the notes at the top of the forum and a few of the posts before had you done so you would have known better. As for the rest you need to study the instructions for your 'bot.

15  Products / Arduino Due / Re: How to connect SD card reader to Arduino DUE - help needed on: September 13, 2014, 05:41:33 pm
You can't using Adafruits software as it is not designed to run on the due.
