#140076 - What is type of your motor? Responding to: ???'s previous message |
If you use bipolar stepper motor it is better not used uln2003
because this IC has open collector output so you need small resistor for probably high current capability. We assume you using unipolar stepper.so are you sure your port pins works properly? are you sure you generate right sequence to your stepper? did you see generated sequence on an oscope? Anyway i recommend you to use l298+l297 configuration because this tow component have current chopping and sequence geration so they are really complete for most of applications . |
