Control bipolar stepper motors
It's right - we already had stepper motors (Application note 018). But there is good reason to recall this topic. One is that we then built a discrete solution for the motor output stage, now we try a more elegant approach with the H-bridge IC SN754410, which we successfully tried with small DC motors (Note 059). Another reason for the new beginning is, that we want to control bipolar stepper motors this time, which have a simpler structure and are less expensive.
Switching off the Tiger when not in use
Did you ever turn down a battery supplied project with the BASIC-Tiger, simply because it uses to much current? This is especially annoying when the BASIC-Tiger is supposed to work only now and then in the planned application: Yet its current consumption is rather high even in idle times. Think about e.g. a control with two small motors, which have to sensitively swing and rotate a video camera. Once you have your object in focus, all motors stop. Yet the BASIC-Tiger want ca. 50 mA and this is not acceptable for batteries for longer durations.
Motor control with H-bridge
Do you remember the experiments with DC motors from application note no.19? You like to relieve the BASIC-Tiger or simply control a larger number of motors (e.g. for robotics projects)? Then this application note shows a clever solution how to control up to 62 motors in both directions with 127 speed steps each with moderate computational effort and minimum pin requirement.
