Hello all i am a newbie here,

well i have been given this schematic as a challenge (attached)
i have no previous experience writing in program for pics
my assignment was to write a program that would turn the motor on for 6 sec
if the switch was pressed.

Welcome.

No experience at all...
Lets start off by finding out what too;s you have to work with.

Programmer?
Pic Basic or Pic Basic Pro?
Do you have MPLAB installed?

We normally like to start folks off with an LED blinking program, but yours also looks like a good one to start with.

One of the first things you need to understand is how to configure the PIC.
This thread will help you there.

The basic code for you app.


LOOP:
IF PORTx.x = 1 THEN 'Switch pin
HIGH PORTy.y 'Motor pin
PAUSE 6000
LOW PORTy.y
ELSE
LOW PORTy.y
ENDIF
GOTO LOOP

Hi, Northdelights

First of all, Welcome here.

I remember having built such a circuit 10 years ago ( goal was to power a soap pump for 3 secs ... more if finger kept on button ) with a single 555 timer as a monostable multivibrator.

As the case is the same ... you can make the 555 look like a pic ...

honour will be saved ...

Thank you dave for the advice and for also providing the code for me that was kind of you.
Ill look into it alittle more to determine how you get there and how label each pin

Hello northdlights,
Welcome,
Here are some links that are really going to be "assigned reading" because you absolutely need to know this. You would do well to avail yourself of all the links in the <b>FAQ</b> section available from the forum home page. Probably the most difficult thing to learn is how to interpret the data sheets

When you go to the FAQ section you may need to set the Display Options at the bottom of the page to show threads from the beginning.
