Word file Circuit 89 – Stepper Motor (Multi-Step)
The motor runs from a 12V supply, and draws a fairly heavy current in the region of 300 mA depending on the torque required. The pulses to operate the stepper motor driver provided by 555 (astable circuit) are now fed to pin 15 of the SAA 1027 chip via a transistor, and for each pulse … Access Full Source

CIRCUIT DESCRIPTION We have designed the kit so that the stepper motor can be run continuously at a fast or low stepping rate then, when it nears the desired position, it can be switched Check the 555 IC is in the correct way.
