Hi guys!
I need a little help too.
I want to know which cell models support SMS TEXT mode ?
I know, lot of cell phones can operate in PDU mode, but I want to know the TEXT mode like t290 from Sony ericsson,
Please List as much as possible, Because I am not sure, Whether I'll be able to get any...
you provided a scematic of NPN's, but do i always have to use in Darlington form,
can i not use as single form, not in darlington configuration??

and next
i got a L298n IC,
now any suggestions, from where should i...
understood that very well,
that's great.......
@@@@@@@@
now that was the real problem, i had,
after seeing the connections you made to motor, this came to my mind, and i composed a paint file to ask you the same thing , ( file is attached ), but now i had understood that..........
thank you...
yes boss!
it is tested and found working,
really thankfull to you......
i have just 2 more questions, 1st is that, what might be the reason that my circuit was not working?? after i have changed the circuit just like your's except the addition of resistors(resistors not installed) ??
although...
understood very well,
ok, this means, i have to generate some small delay, like some hundred cycles.....
thanks once again,
i'll reply in 2 hrs, after i make and check the working....
thanks
Sorry bro!
I mistakenly wrote "Collector" in place of "Emitter".
Please read my above post once again, as it is re-edited.

I have already done that, but of no success...........
Which version of Proteus are...
Boss, i got your point of Current limiting resistors, and i had also a loook at your refered Links of H- bridges, but
as above you have mentioned that
"
" but when i take my voltages of emitter lower than the BASE, still it won't work,
I have also made the Motors operating voltage less,
Still...
hi to all,
help required in driving Bipolar stepper using uC in Proteus only,
i am assigned to drive a bipolar stepper motor in proteus simulator,
after reviewing much literature, i got to the point of designing, but still no success, as motor is not turning, the logic is working right,(as it is...
Thanks sir,
i am cleared on the point, I have checked the motor by giving pulses to its coils in specific sequence and it works as desired,
Now i just want to ask,
which switching transistors should i use for switching in motor??
I want to use discrete components, no ICs, So please list me some...
what do u mean by Dual H-Bridge??
do u mean that there are 2 poles so we need one H- Bridge for each Pole??
i was started on thinking like this because 4 transistors were required for a single H-Bridge like:
SEE the attached link........
Driving Bipolar Stepper Motors
and if there are 2...
i am trying to drive bipolar stepper motor, i have got no special bipolar stepper motor driver IC, instead i m using a Power supply which can give current upto 1A,
first of all, i found resistances between different terminals,
which found to be...
RED-------9.7 Ohm-----yellow
orange----9.7...
