how to create robot car with sensor temp ??

i was there to make a robot car project using arduino with temp.sensor....
can anyone help what kind of tools and code program???

i was there to make a robot car project using arduino with temp.sensor....

With a temporary sensor? Wouldn't a permanent one make more sense?

can anyone help

Sure. I'll be right over. Where do you live?

what kind of tools

A chainsaw and an ox-acetelene torch, to start with. A CNC mill is almost essential, too.

and code program?

What is the robot car supposed to do?

make a robot car fire but use a fan instead of water ...

That's a good idea. If you use water, you'll put the fire out. Using a fan to make it spread is a much better idea. Before long, your whole robot will be burned up, and you can move on to projects that make sense.

no no no im sorry for that stetment i was wrong...
my project measure the temperature in the room and if the temperature exceeds the set temperature then the fan will turn on ...
that's it i mean :slight_smile:
first i want a motor dc can be set start or stop using arduino....but i don't know the code programm :frowning: can help ?

How is the motor connected? Do you want just on/off or variable speed?

Some references that will be useful:

On/Off - http://arduino.cc/en/Reference/DigitalWrite

Variable speed - analogWrite() - Arduino Reference

thanks before , but i was try with motor dc is not connected … what is using transistor ???
