How would I set this up with the peltier plate and Arduino to control temperature and also reverse the current?You would be better getting one

Peltier Plate Current Reversing and Controlling the Current with Arduino Uno
I bought it but I'm getting it tomorrow since I need it urgently D:, so a 12V battery would be enough to supply this and a peltier plate?
If you could show me how it would be wired asap that'll be great! Thank you so much again
I want to reverse current of peltier plate, and also with the ability to control the current so I can control only hotness once I reverse the current, or control only coldness if I did not reverse the current.

The H-Dual Bridge Motor you suggested: http://www.robotshop.com/en/dual-h-...hZjfE_z5YlB2o_UzcICMq_2LwddUU-cBoC3F8QAvD_BwE
An Arduino Uno

What if I use 15V instead would that be okay?
Thank you so much I ordered it and it's coming tomorrow
Ho
I'm not sure how to program this with the Arduino would it be the exact same?
Okay! Thanks man
Here the code for how a motor would work with the h-bridge.
It's there sample.
Don't get hung up on the motor you do about the same thing to use the peltier
You power the wires one side high one low and pwm the power to set how cold you want.

Code:
int i=0;
void setup() {
// Motor_1 controll pin initiate;
pinMode(4, OUTPUT);
pinMode(5, OUTPUT);
pinMode(9, OUTPUT); // Speed control
// Motor_2 controll pin initiate;
pinMode(7, OUTPUT);
pinMode(8, OUTPUT);
pinMode(10, OUTPUT); // Speed control
//Enable the Motor Shield output;
pinMode(6, OUTPUT);
digitalWrite(6, HIGH);
}
void loop() {
digitalWrite(6, HIGH);
digitalWrite(4, HIGH);
digitalWrite(5, LOW); // Set the rotation of motor_1

for(i=20;i<250;i=i+5)
{
analogWrite(9,i); // set the motor_1 speed ;
analogWrite(10,i); // set the motor_2 speed ;
delay(200);
}
Serial.println("stop 3s");
digitalWrite(6, LOW);

}Is there anything I should be aware to prevent from damaging the peltier plate in the code??
Sorry to bother but I need urgent help :// since this project is almost due how would I make it so that the power goes to the peltier plate until I turn off the system?
I haven't looked at the code at all but I'd be nervous about switching current direction at full power, because of the potential for thermal shock that might damage the TEC. I don't know how serious a problem this is and have no recommendation for the proper time to allow between switching states. It just seems to me that a time of zero might be a problem.
wayneh I'm with you on that.
I've looked not found much telling a set time.
This is what I have found you read the plate temp and when it's at it normal state
you switch the current.
http://www.analog.com/media/en/tech...cles/37488110918229TEC_Application_Brief2.pdf
There using Temperature Acquisition and Closed-loop Control
First off make sure you hook it up Like i showed in post 49
I'll post you code to test that and then you can go from there.
Don't run the code you posted you want test it first.

Thanks man I appreciate it
This is all you need to use for the one h-bridge on A
It stops 3 seconds between changes you maybe need more time.

}I want to make sure that it doesnt break my peltier plate
