i make the connection in the schematic and the motor works perfectly, this is really helpfull.
the problem that i put an LED in each output of the driver and when i take it off the motor works and drived very will by the ULN2003A
thank you
thank you friends,
i forget to tell, the motor is a unipolar stepper motor and it has 5 wires (4 phases and 1 GND). so which motor driver is the best? H-bridge IC (SN754410) or ULN's?
i used a schemit trigger to convert the outputs of the uln2003a from low (0.6v) to high (5v) and then connect it to the motor and it works. i think i will need voltage regulator if i want to increase the voltage more.
thanks
Hello friends...
i want to interface the ULN2003A with 12vdc stepper motor, i put a 5v in the inputs of the motor driver (5v for each in a sequence) but the output of the motor driver is low (0.6v) and cannot move the motor of course.
i change the ic and also increase the input voltage and...
sparky2 thank you for the useful tips :D
Syncopator thank you very much this is very helpful to me :), which value of the diode i should use?? can i use 12v diode ?
thank you alot andre for the information.
can i use voice recognition kit such as SR-07 Speech Recognition circuit? to control a stepper motor or any devices?
or the DSPIC will be a great choose ?
Hi friends...
i need a dsp for my voice recognition home project,
are there a dsp that already built with voice recognition code, so i can use it directly and connect it to my project?
also, what is the cheapest and easiest dsp i can use in voice recognition??
