Using the L298N driver, we will connect a bipolar stepper motor to the Arduino board. For control, we will use the programs from the previous lessons for unipolar motors.
It is one of the main and most popular products of the new V20 series of filling equipment.
In all the articles on stepper motors, I never tired of repeating that a stepper motor combines an electric drive and a positioning device without feedback. In this lesson, I want to demonstrate the use of a stepper motor in an electric drive positioning system.
In the lesson, we will develop a stepper motor driver with computer control. I will talk about text-based communication protocol using AT commands. We will learn how to control a motor using the Arduino IDE serial port monitor and the top level program StepMotor.
In the lesson, I will tell you about text strings in Arduino, about the String class, about converting various data types to text strings, and about the reverse operation-converting strings to numbers.
In the lesson I talk about my StepMotor library, designed to control unipolar and bipolar stepper motors.
With this publication, I begin a series of lessons about stepper motor control in the Arduino system. The first lesson is devoted to connecting unipolar stepper motors to Arduino.
In many of my developments, I use stepper motors. There are branches of precision mechanics in which they are irreplaceable. I will try to explain as simply as possible how the stepper motor operates, what it is.
A series of articles about temperature measurement using Arduino controllers would be incomplete without a story about thermocouples. Moreover, there is nothing else to measure high temperatures.
In the lesson we will learn how to connect a DS18B20 temperature sensor to the Arduino board, how to control it using the OneWire library. We will develop an accurate thermometer.
