8051 stepper motor interfacing with programming in proteus

In this article we will learn how to Interfacing 8051 stepper motor with programming in proteus.

In the last post we will learn how to interfacing 8051 interfacing with external Ram and ROM in Proteus. You can visit our website,
I hope you appreciate my work, let’s discuss about today’s project.

 

 

Components:

1. IC (8051)
2. IC (ULN2003)
3. Servo motor (12V)
4. Resistors (10k, 1k, )
5. Diod (4148)
6. Capacitor (30pF, 22uF)
7. Crystal (1.2MHz)
8. Push button
9. Jumper wires

Construction…

• Connect pin 9 of 8051 with +ve side of capacitor 22uF through one side of Resistor 1k
• Connect –ve side of capacitor 22uf with +ve
• Connect 2^nd side of resistor 1k with GND
• Connect pin 31 of 8051 with +ve
• Connect pin 9 of ULN with +12V
• Connect Terminal A of Servo motor with pin 16 of ULN(2003)
• Connect Terminal B of Servo motor with pin 15 of ULN(2003)
• Connect Terminal C of Servo motor with pin 14 of ULN(2003)
• Connect Terminal D of Servo motor with pin 13 of ULN(2003)
• Connect signal terminals with +12V
• Connect one terminal of Forward button and +ve side of 1^st Diod with GND
• Connect 2^nd terminal of Forward button and –ve side of 1^st Diod with one side of Resistor 10k
• Connect 2^nd side of resistor 10k with +ve
• Connect one terminal of Reverse button and +ve side of 2^nd Diod with GND
• Connect 2^nd terminal of Reverse button and –ve side of 2^nd Diod with one side of Resistor 10k
• Connect 2^nd side of resistor 10k with +ve

Working…

Interfacing an 8051 microcontroller with a stepper motor involves controlling the stepper motor to make it move in a precise and controlled manner. Stepper motors are commonly used in applications that require accurate position and speed control.

Applications…

1. Robotics

3. Telescope and Camera Mounts
4. 3D Printing
5. Textile Machinery

Advantages…

1. Precise Control
2. Low Cost
3. Simple Interface
4. Reliability
5. Low Power Consumption
