I'm having trouble . I couldn't figure out how to write a program to use temperature sensor to give out 3 different kinds of voltage to a motor . Could anyone guide me in this ? By the way , I'm using PIC18F4550 microchip in it .

There's not much chance of that without say a circuit diagram showing how your sensors and motor are wired to your PIC.
The circuits are basic type . Normal temperature sensor circuit and DC motor circuit .
Oh that's a relief then :rolleyes:
For a moment, I thought you had the sensor wired to pin2 rather than pin1
Shouldn't that sensor be on pin 3?
So how should I write the program ?
Well we could spend a few more days trying to tease every small fact about the problem using this method
Or you could read this and provide us with a decent amount of usable information about what you're actually using, what you're actually stuck on and what you've actually tried so far.
THIS is an example of a troll.Quote:

I'm trying my best dude . There's no need for sarcastic remarks .

Also provide information as to who manufactured the sensor, along with model number. How manufactured the processor board and its model number would also be helpful. What compiler are you using?

I'm using MCC18 compiler . Is it possible for me to post the picture of my sensor and all here for you to see ? Cause some part of it , I'm not too sure of it .Quote:

Anyway I will be connecting the temperature sensor to portb .
schematic_MCT_board.pdf
this is the schematic of the PIC I'm using .
If you don't know what the hardware specifications are, you need to contact whoever gave you this project. Since you don't even seem to know the difference between C and C++ I doubt you will get very far with this project without serious hand holding. Good Luck.
But I'm sure that it's C++ programming .
From the first link in a Google search of MCC18.
You are using a C compiler, a C compiler does not compile C++ code.Quote:

Really?
I mean, you can already do something like attach your motor to your MCU board, and have written some software which reads say switch RB0 to move the motor one way, and reads RB1 to move the motor the other way.
I'm not so sure you can do that already, since I don't think you've ever written a program for it before.
You need to just practice writing programs which do simple things just on the board.
- light RD0
- light RD0 to RD2 in sequence
- light RD0 to RD2 in "traffic light" order.
- light RD0 if RB0 is pressed
It's all about getting familiar with the tools,
- how you use the editor to write code
- how to use the compiler / linker / loader
- how to get your program onto the MCU to begin with
- how to figure out where it went wrong (you have NO debugger to help you here, no printf to report progress or anything).
I have no trouble writing the part for motor cause mine is one way and I only need to send different voltage if the temperature is different . The light RD0 all , I've done it before . The only trouble I'm having is the AC to DC converter for the temperature sensor . I don't know how to get the figure out .Quote:

So, he likely needs to do analog to PWM.

Sorry . I think it's converting analog to digital .Quote:

Two different languages. Very easy to tell them apart.
Considering this is a C compiler, you will obviously be using C, and not C++.
