Fritzing stepper motor
Fritzing stepper motor series#
As 13.56MHzhighly integrated card reader series chip new family, the MF RC522 MF RC500 MFRC530 there are many similarities, but also have many of the characteristicsand differences. MFRC522 support MIFARE series of high-speed non-contactcommunication, two-way data transfer rates up to 424kbit / s. Inaddition, support Quick CRYPTO1 encryption algorithm, the term verificationMIFARE series. Thedigital part handles the ISO14443A frames and error detection. The MF RC522 use of advanced modulation and demodulation conceptcompletely integrated in the 13.56MHz all kinds of passive contactlesscommunication methods and protocols.
Fritzing stepper motor portable#
MF RC522 is used in highly integrated 13.56MHz contactlesscommunication card chip to read and write, of NXP for “three” and theapplication launched a low voltage, low cost, small size, non-contact card chipto read and write, intelligent instruments and portable handheld devicesdeveloped better.
Each tag has his own identification (UID). Ø tags attached to the object to be identified, in figure keychainand an electromagnetic card. For example, only theperson with the right information on his card is allowed to enter. RFID is useful toidentify people, to make transactions, etc… RFID useselectromagnetic fields to transfer data over short distances. RFID means radio-frequency identification. Ø Programmable Watchdog Timer with Separate On-chip Oscillator

Ø Byte-oriented 2 wire Serial Interface (Philips I2C compatible) Ø Six channel 10 bit ADC including temperature measurement Ø Real Time Counter with Separate Oscillator Ø One 16-bit Timer/Counter with Separate Prescaler, Compare Mode, andCapture Mode Ø Two 8-bit Timer/Counters with Separate Prescaler and Compare Mode The main processor on Arduino UNO is an ATmega328 microcontroller which includes the following features: Ø Flash Memory: 32KB (0.5KBused by bootloader) Ø Maximum DC Current per I/I pinat 3.3 VDC: 50ma Ø Maximum DC Current per I/O pin at 5VDC: 40ma Ø Digital I/O Pins: 14 total –6 of which can be PWM Ø Uno Board Input Voltage Limits: 6 – 20 V Ø Uno Board Recommended Input Voltage: 7 – 12 V The board can be powered from the USB connector (usually up to 500 ma for all electronics including shield), or from the 2.1 mm barrel jack using a separate power supply when you cannot connect the board to the PC’s USB port.the Arduino UNO has the following specifications: the system block diagram below shows the system components that used in design and implementation of the proposed RFID access control system. A 16x2 LCD display is used as output component to show different situations of the system, also an electric buzzer or a piezo transducer is used to generate system sounds and alarming indifferent situations, a LED is used as indicators also with different situations, and finally a push bottom is used for admin to erase the EEPROM of the microcontroller, the implementation also uses some wires, jumpers, and breadboards for testing the functionality of the system. RFID-based control system design is based on microcontroller control system which by using Arduino UNO that works with ATmega328P microchip which is fully suitable for such applications, the RFID module used is MFRC522RFID module which is a reliable and compatible component to work with Arduino's boards, for door control a 28BJY-48 stepper motor is used that can be controlled in both directions and also number of steps and speed can be controlled, the stepper motor is derived using ULN2003 high voltage, high current Darlington array Integrated circuit.
