Where to use 28-BYJ48 Stepper MotorThe stepper motor utilized in this project is the most commonly used 28-BYJ48 Stepper Motor shown above fig 9.

The motor has a 4 coil unipolar arrangement and each coil is rated for +5V and can be easily controlled with any basic microcontroller. You can find this (or similar) motors in your some basic everyday items such as those listed below.Stepper Motor Applications• CNC machines• Precise control machines• Security cameras• DVD Players• Car side mirror tilt• Closing a valve for this projectThis motor has a stride angle of 5.625°/64, this means that the motor will have to make 64 steps to complete one rotation and for every step it will cover a 5.

625° hence the level of control is quite high. These motors run only on 5V so don’t expect very high torque, for a high torque application you should consider the Nema17 motors. Normally you would have seen servo motors being used to shut off valves in industrial applications .

Now the stepper motor can do the same job with greater control in terms of flexibility and is cheaper, not taking anything away from the servo motor. How to use 28-BYJ48 Stepper MotorThese stepper motors consume high current and hence a driver IC like the ULN2003 is mandatory.
