Will this fry my Arduino?

Below is a picture of the Arduino Mega powered with a 9V battery. On top the board is a WiFi Sheild, and on top that is a MotorSheild Also Powered by a 9V battery. The shield will run a 12V 200x Stepper Motor. I also have a LED Strip wired into pin6 and power leading into the MotorShields 5V and Gnd pins. The LED strip is powered on one end with a 5V wall-wart.

I notice the pins for 5V and Gnd go to the Arduino pins for 5V and Gnd. Will this be to much power for the Arduino board to handle?

Also I might up the 9V battery on the Sheilds screw terminals to something larger like 12V.

If this is too much power leading into the Arduino, what must I do?

More than 12V will probably fry the Arduino, but those dinky little 9V batteries will only run
it for a few hours. Also, they'll probably run the wifi board for a lot less time. In general,
it's best to use separate batteries to power Arduino and motors, as this will help keep the
motor electrical noise off the logic, but either way, you will want some filter and bypass caps
on the motor power terminals.

I use NiMH AA-cells in wired series to power my portable Arduino apps. A 12V SLA might be good
for the stepper.

I am new to electronics, so I am still unsure if what I am doing is correct.

Is that what I did with the 9V source going to the Aduino AND Motor terminal? Keep in mind, I also have a 5V source feeding to the LED Strip on the opposite end (of what is plugged into the Arduino 5V and Gnd)

but either way, you will want some filter and bypass caps on the motor power terminals.

I'll have to research this and I'll comment back accordingly.

If your motor require more than 9V we recommend that you separate the power lines of the shield and the Arduino board on which the shield is mounted. This is possible by cutting the "Vin Connect" jumper placed on the back side of the shield.

I scraped off the connecting jumper strip on the back of the board to limit the current going to it and only affecting the motor. I severed the Vin Connect jumper shown in the lower left (Right most leads) of the image below.

How many, 8? Max voltage on the Mega is 12V
