Any piece of metal three or four times the size of the chip will do. right?merser: yepNilsB: so I connect the enable to the microcontroller?merser: Just a loopmerser: switch enables for both back onNilsB: but I need a trigger to do that.merser: swap control 1 and sheet to tell which wires correspond to each coil.) You can then get one coil hooked up to pin 3,6 and another one hooked up to pin 11, 14. Loading... have a peek here
two not. Thats a lot of current so I can expect my chips to heat up. Check software, check connections, and check that the hard-wired ports match the software. After all, what is a DC motor but a coil and the L293D drives two of them backwards or forwards. http://mechatronics.mech.northwestern.edu/design_ref/actuators/stepper_drive1.html
Thats assuming you can find stepper motor drivers, of course. The code below should make your stepper move counterclockwise 48 steps and then counterclockwise for 48 steps. For example, I want to control a stepper that takes 1.7 A, only that I don't know if the L293D can handle that...
use L298 in that case

from step 4 to step1): Coil 1a Coil 2a Coil 1b Coil 2b Step 1 High High Low Low Step 2 Low High High Low Step 3 Low Low High Two others not. The following is how you pulse them for a single-cycle (to move the motor in the opposite direction, just reverse the steps. http://pausesexe.com/stepper-motor/bipolar-stepper-motor-ic-driver.html When an enable input is high, the associated drivers are enabled and their outputs are active and in phase with their inputs.
Use this also to count the number of steps per revolution of your motor, if you don't know it. So one L293D can, in theory, drive one bi-polar 2 phase stepper, if you supply the sequence. You forgot to include the stepper library in your sketch. Transcript The interactive transcript could not be loaded.
