i need help here,
can anyone guide me to wiring this type stepper motor [Product Code : MO-STEP-17PM-K508]
which one wire control clockwise/counterclockwise
which one command.
the color of wire blue,orange,black,yellow,red and brown
i can't drive this stepper motor using TIP41C

hope anyone help me. Thanks you

Why can you just try and modify the code? The board will not explode.....
Anyway if you like to read one channel only, change the subroutine to read channel 0, no more parameter needed when calling this subroutine....

For part B,there had 2 channel due to it had gas and humidity sensor.


if i only had humidity sensor,do not had gas sensor, so i just need direct set CHS123 to 000??

Tomorrow (18 Nov 08) ASIMO from HONDA will stop by UTM for a short introduction. UTM will aslo show their own developed Humanoid Robot!

fiq, which part of code that you do not understand? Is hard for member to explain the whole code to you. Thanks

Part A is actually 2 sub-functions. 1st function is to make the LCD clear. 2nd function is to send a string to LCD. sending string is actually sending character one by one. This function used pointer to point to string. Just compile the code using PICC Lite like any DIY project will convert this code to machine code, if that is what you need.
Part B is another sub-function that return ADC result base on channel wanted. CHS is actually the channel select bit, these 3 bit will control the channel connected to ADC module on PIC. please refer to data sheet of PIC16F877A, find ADCON0.

Thank you, robosang, for your comment.. im already check the resistance coil..that unipolar..im not going to use bipolar because require transistor to drive it..

robosang, what are you laughing at? Wanna shoot people again? Hehe :)

fiq, I thought the code is already explained in the comment? Isn't it?

muhzd, you can try this: http://www.sparkfun.com/commerce/product_info.php?products_id=8745. Is a logic converter from sparkfun! Pretty nice piece of work!

Azka, I have one of this stepper motor long time ago, but is not from Cytron, get it from some place in pasar road. I cannot remember the model name, but it look the same with what Cytron have. and is unipolar, of course you can drive it using bipolar method. Is good to have unipolar stepper motor where you can drive it unipolar or bipolar. Good luck to your project!
