TYPICAL APPLICATION

Digitally controlled as part of an open-loop system for use in holding or positioning applications
In the field of lasers and optics, they are frequently used in precision positioning equipment such as linear actuators, linear stages, rotation stages, goniometers, and mirror mounts. Other uses are in packaging machinery and positioning of valve pilot stages for fluid control systems.
Commercially, stepper motors are used in floppy disk drives, flatbed scanners, computer printers, plotters, slot machines, image scanners, compact disc drives, intelligent lighting, camera lenses, CNC machines and, more recently, in 3D printers

SPECIFICATIONS

Stepper motor

Operating voltage – up to 15 v

This Motor has a Gear ratio of 64, and Stride Angle 5.625° so this motor has a 4096 Steps.

Steps = Number of steps in One Revolution * Gear ratio.
Steps= (360°/5.625°)64″Gear ratio” = 64 64 =4096. This value will substitute it on the arduino Sketch

CIRCUIT DIAGRAM

The circuit is sectioned into 2 parts

The Button Section
The Stepper driver section

Step 1: Button Section

Connect the 2 negative rails of the breadboard to the ground pin of the Arduino,

Then connect the 2 positive rails of the breadboard to the 5v pin of the Arduino.

Let’s start off with the button section.

Place the button on the breadboard (In the final slider there are 2 contact points that will be closed once the sliding unit reaches either end).

Connect one end of the button to the positive rail
Connect the other end of the button to the ground using the 10K resistor.
Connect pin 3 of the Arduino to the intersecting point of the button and resistor.

Step 2: Stepper Driver Circuit

Now let’s start building the stepper driver circuit

(It’s important to note here that the transistors must be able to handle the max current draw of the stepper motor, you can find this info on the datasheets).

Place a transistor on the breadboard

For the pn2222 transistor, the first pin is the Emitter, connect the Emitter pin to the ground rail.

The collector is the 3rd pin on the pn2222, connect a lead to the Collector of the transistor and let it hang (We will be using this to connect the stepper motor later).

The middle pin is the Base, connect an LED to the Base of the Transistor and another terminal strip.

Connect one of the 220 Ohm resistors to the LED and to another terminal strip.

Connect a lead between the resistor and the Arduino.

Repeat this process until you have 4 of these “Electronic switches” connected to pins 5, 6, 7 and 8.

Step 3: Connecting the Stepper Motor

Moving on to the connection of the stepper motor.

Connect a lead between the positive rail and the positive of the stepper motor.
Connect the leads hanging in the breeze to the stepper motor.

Ensure to connect the leads using the order found in the datasheet of the stepper motor.

WORKING

This program runs the stepper motor and decides what to do when the button is pressed.

The program continuously checks to see if the button is pressed.

The motor goes in one direction until the button is pressed down then the motor will reverse its direction and keep on going in that direction even when the button is released.

If the button is pressed again it will reverse its direction again.

In the motor control section of the program.

It follows a sequence of sending a signal to the pins on the Arduino and in turn switches the LEDs and Transistors on and off to make the motor step to that sequence.
