user34980: I'm actually working on a robotic project for which I'm planning to use arduino to drive the wheels.For this, I want to send signals from my Onboard embedded computer (which has Windows Embedded Compact 2013 OS) to arduino. Is this possible? If not possible, what are the other alternatives?  

user31105: What OS is running on two different devices exchanging messages/signals, does not matter. What matters is the protocol. 
You can use a lot of different ones:

Wireless:


IR (infrared)
RF (radio), like 433 MHz, 2.4 GHz
WIFI (internet)
Bluetooth

Wired


SPI
'simple wires' / Wire library
Serial
USB (not on most Arduinos)


This list is not complete, just some examples.
Arduino supports all above (except USB fully), I don't know what Windows Embedded Compact OS supports.
