Give us a starting place, please share the code you have.

DCtoDC converter is a good recommendation.
Also driving the motors with a relay or optoisolator/MOSFET combination is advisable, take your motor grounds to the battery terminal with a separate ground run for the Arduino.
Use some sort of spark arrestor, MOVs diodes capacitors for the DC motors.

digitalWrite would take that pin out of PWM mode so you do a analogWrite to put it back

4xAAA alkaline would be 6 volts -.7v for the diode, a bit low for vin to work properly.

You can do that.
291  Using Arduino / Programming Questions / Re: direct port manipulation --analogeWrite on: March 22, 2014, 07:17:20 pm
Motors react slow compared to the speed of the Arduino.
Show us your code, it may be the way it is written that is the problem.

Appreciate all the work you are doing.
Thanks for sharing it with the community!

You aren't showing us the sketch.
296  Using Arduino / Microcontrollers / Re: Arduino Pro Mini / Not sure if I wired this correct? on: March 19, 2014, 01:32:40 pm
If the output of the battery is 5 volts connecting it to raw will be a problem.
I believe you can connect it to VCC directly.
Perhaps others can confirm this.

Edit :
Nice neat draw drawing.

Type "byte" use eight bits.

 float tempC;
You have to assign something to tempC before the if statement.
   if (tempC <= 21.11)
