Circuit: Stepper Motor

July 12, 2007

This is a neat little one-chip circuit we originally tuned for use with our "SM1" Stepper motors. We've presently sold out of the motor, but this circuit has proved to be a good unidirectional (1-way) driver for small stepper motors. Parts required are:

  • 74AC240 Octal buffer chip
  • 4 x CP0.1µF capacitors
  • 100k resistor
  • 2 x 47k resistors

We've just released the CMDR (Compact Motor Driver) Shield, which lets you bi-directionally drive two gear motors or a single stepper motor, read 6 analog sensors, and control up to 8 servos all at the […]

So there's one link today that makes my artistic soul happy - it is the laser-controlled Etch A Sketch. Although I never owned an Etch A Sketch (some smarty pants might say right here that in Russia we used rusty nails to draw on cardboard instead), but the idea to draw with a laser beam […]
