Now join the IN1, IN2, IN3, IN3, and IN4 pins of the driver module with the digital-8, digital-9, digital-10, digital-11 pins of the Arduino. Attach the GND pin of the Arduino with the GND pin of the driver module.Connect the 5 volts pin of the Arduino with the VCC pin of the driver module.You can also read our article on it to understand the connections.Make the connections between the pins of the Arduino and 16×2 LCD as shown in the diagram.

Make the connections according to the given circuit diagrams and then upload the code. SO, basically we are controlling the stepper motor with Arduino. When the stepper moves in a clockwise direction a text is appeared on the LCD screen informing the same and when it moves in the counterclockwise direction, the text will display status. You can make any of them as per your choice. There are three circuits given below along with the codes. In this article, we are going to make a stepper motor controlling circuit using Arduino UNO and ULN2003 motor driver. Can we control the RPM and direction of a stepper motor? Can we directly connect a stepper motor to the Arduino? What makes a stepper motor different from an ordinary motor? Simple Circuit for stepper motor and arduino.Circuit for Stepper Motor Controller /arduino with stepper motor circuit.What is a ULN 2003 stepper motor Driver.The connected stepper would rotate with a changing direction for this progam. Motor_LR() //make the stepper to clockwise rotate Motor_CCW() //make the stepper to anticlockwise rotate Void Motor_CW() //the steper move 360/64 angle at Clockwise Void Motor_CCW() //the steper move 360/64 angle at CouterClockwise The following picture is the control signal to drive a 28BYJ48 stepper to rotate 1/4096 circle.īyte CCW = Ĭonst int stop_key = 14 //stop_button connect to Arduino-A0īyte change_angle=64 //change the parameter to change the angle of the stepper The following picture is the schematic of the stepper driver. And you also can control the speed of the stepper rotate by the frequency of the pulse.

you can control the angle the stepper moved by the number of the pulse. So if you give stepper driver a certain pulse signal, it will drive step motor to a certain angle.

Step motor is to a machine to convert pulse to angle displacement. Operating temperature: -25 degree Celsius ~ +90 degree Celsius.it can sink 500mA from a 50V supply,but you'd better limit the driver voltage under 15v.The most easy module to learn how to control the Stepper and finish the simple project.It used ULN2003A to amplify the control signal from the Arduino. The Mini Stepper Driver is small size and easy to use.
