Servo ON and OFF through RFID-RC522 circuit in proteus

Servo ON and OFF through RFID-RC522 circuit in proteus

In this article we will learn how to make Servo ON and OFF circuit trough RFID-RC522 in proteus.
In the last post we will learn how to make Motor Shield V2 motor party circuit in proteus. You can visit our website,
I hope you appreciate my work, let’s discuss about today’s project.

 

 

 

Components:

1. Arduino UNO
2. LCD display
3. IC (PCF8574)
4. Servo motor
5. Jumper wires

Hardware Image…

Construction…

• Connect pin 3 of Arduino with signal pin of Servo motor
• Connect one terminal of servo motor with +ve
• Connect 2^nd terminal of servo motor with –ve
• Connect A0, A1, A2 pins of IC with GND
• Connect SCL pin of IC with A5 pin of Arduino UNO
• Connect SDA pin of IC with A4 pin of Arduino UNO
• Connect VSS & VEE pins of LCD display with GND
• Connect VDD pin of LCD display with +ve
• Connect RS pin of LCD display with pin 4 of IC
• Connect RW pin of LCD display with pin 5 of IC
• Connect E pin of LCD display with pin 6 of IC
• Connect pin 9 of IC with D4 pin of LCD display
• Connect pin 10 of IC with D5 pin of LCD display
• Connect pin 11 of IC with D6 pin of LCD display
• Connect pin 12 of IC with D7 pin of LCD display

Working…                                                                      

Controlling a servo motor using an RFID-RC522 module and an Arduino is a common project. In this setup, you’ll use an RFID card or tag to trigger the servo motor to move between ON and OFF positions

Applications…

1. Access Control System
2. Cabinet or Locker Lock
3. Attendance System
4. Vending Machine
5. Home Automation

Advantages…

1. Security
2. Contactless Operation
3. Convenience
4. Automation
5. Cost-Effective
