There isn't any "control" of the ground pin - it is just that - the connection to the common ground. If you mean "How can you make a pin on Arduino go to LOW" (which is the same a zero volts of ground), use the pinMode() function to set a pin to OUTPUT and then issue a digitalWrite() command to that pin setting it to LOW
What else can I help you with?
How do you code an arduino to control a servo on a timer?
You will need a sketch (an arduino program), and you'll need to know the interface from the arduino to the peripheral (servo)
What methods can you use to power and control a small electric motor using an Arduino without directly drawing power from the Arduino?
Have the Arduino control a relay that connects an external power source to the motor.
How do you use the tone function on your Arduino?
The TONE function on the Arduino generates a square wave on the specified pin based on the parameters specified. In other words, it quickly turns the pin on and off at the frequency specified. The syntax is:Tone(p,f,d)where p = the pin, f = the frequency in hertz (number of times per second) and d = duration to sound the tone in milliseconds (thousandths of a second). So, if you want to play the note middle C (about 260 hertz) for two seconds on pin 3 you would call:Tone(3,260,2000)In terms of hardware, you would need to connect a small speaker to the Arduino pin, one connection to the output pin (3 in our example) and the other speaker connection to ground (GND).
Is arm and arduino the same?
No, Arduino is AVR. Not ARM.

What is a shield for Arduino and do I have to buy it if I already had an Arduino board?
A shield is essentially a "daughterboard" of a PCB that has pins to match the female pin headers on a standard format Arduino board. You build your circuits/connections of sensors (switches, light, sound, temperature sensors, etc.) and outputs (LED's, displays, etc.) on a shield as an efficient way to mate the inputs/output connections to an Arduino board. A shield is not required but is highly advised as a way to insure solid connections and organization of connections. For more information see:
