Stepper motors are increasingly taking its position in the world of the electronics. Starting from a normal Surveillance camera to a complicated CNC machines/Robot these Stepper Motors are used ...

Here I control the rotation of a Mitsumi M42SP-5 stepper motor (50 ohm) with a potentiometer, using an Arduino Uno. Since the motor needs 12V to work, a ULN2003A ...

* Program to drive a Mitsumi M42SP-5, 50 Ohm, stepper motor. * The motor has 7.5 step angle (48 steps for 360 degrees). * The rated voltage is 12V. * The excitation method is 2-2 phase excitation with ...

A stepper motor is a type of DC motor that works in discrete steps and used everywhere from a surveillance camera to sophisticated robots and machines. NEMA 17 stepper motor has a step angle of 1.8° ...

Potentiometers, or variable resistors, are a standard component that we take for granted. If it says “10k log” on a volume pot, than we fit and forget. But if like [Ben Holmes] you are modelling ...
