When a person is looking to add additional features and drivers to their devices they can add the ULN2003 to the Arduino.
There is an easy way to add this for simple installation and a person will be able to have this working in no time. A person will learn how to install this 28BYJ 48 stepper motor with the ULN 2003 driver board that goes with the Arduino system.
To begin this process a person is going to need to enter the Arduino Stepper Library. This is a great place to begin the process and there are not a lot of extra things that will get in the way and mess things up. When a person is accessing this information they will be able to use the AccelStepper Library. This library is not complicated and it will help the hardware.
A person will see the changes and improvements in their hardware. There is a big library and there is a lot of information to choose from. The library is also easy to use and no advanced technical knowledge is needed. A person can even make some modifications so they can fit this system to go around their needs.
- 28YJ 48 stepper motor
- ULN2003 driver board
- Arduino Uno Rev 3
- Male to female jumper wires
- Breadboard (not necessary)
- A/B USB cable
- 5V power supply
To help with the installation process the Arduino IDE software is going to need to be installed if it is not already being used.
ULN2003 Driver Board Information
When a person is completing this installation process there is one good thing to know. The 28BYJ 48 motor is one of the least expensive on the market. While it is not super powerful and may not be 100 percent accurate at all times it is a good motor. It is ideal for smaller projects. If a person is looking to learn how to use a stepper motor this can also be a smart choice.
The motor is automatic and will adjust to the airflow. There is a gearbox that has been building it. While this may reduce the speed it will provide some extra torque. The driver board will fit with this motor and there are even wires connections that will be easy to set up and will be easy to put together.
Wiring the Motor to the UNL2003 Board and Arduino
The wiring portion of this installation is what is going to connect everything. These connections will help everything work properly and there is a space that all of the connections will be able to fit. A breadboard and jumper wires are easy to use to connect the driver board with an external power supply.
If power is taken right from the stepper motor it can lead to damage. The Arduino may damage the motor and the process will not work correctly.
There are IN spaces where all of the wires can be connected. A person should look at a diagram if they need to or exact placement. It is not recommended to use the Arduino as the direct power supply as this can lead to damage. It will also lead to poor performance if the Arduino is powered with just the USB connection.
During the connection, it is best to use an external 5 V power supply so that everything will continue to work properly. A person will need to remember that they will need to connect the GND with the Arduino and the pin that will connect this to the ULN2003 driver board.
There will be a code that a person will then upload. They will need to power the Arduino so that it will work. The jumper that is next to the power connection on the driver board may need to be used in this process. In some cases, it is best to disconnect this until the installation is complete.
Connect the components! 🙂
Arduino and Codes
To help the Arduino control the 28BYJ- 48 stepper motor and will help the system run smoothly there is a code that needs to run through the system. To upload the code the Arduino IDE must be uploaded into the system. A person can use the Stepper.h library since this should have already been installed on the Arduino.
With this code, the motor should be able to make a full revolution. This will allow the system to link up. Once this happens the Stepper Class should be entered using the function Stepper (steps, pin1, pin2, pin3, pin4) and there should be a revolution to make sure the motor was properly connected.
Working the Codes
To speed up and set accelerations and decelerations several codes need to be entered into the new system. A person will begin to do this by entering setAcceleration (). This will also allow the motor to rotate and to find its ideal position. To help with this the moveTo () command can be used besides the runToPosition () command.
This will help the motor speed up and slow down on command. This will also help the motor reach its ideal or the target position. This will allow a person to know how fast or how slow they can run their motor and the ideal position for it.
This guide will help a person make sure everything is installed correctly. All they need to do is follow the directions and enter the code. A person will then be able to have this installed in no time at all.
