This Arduino RFID Door lock system consists of an Arduino Development Board (Arduino UNO, Arduino Nano or other), an RFID reader module and an actuator like servo motor or solenoid lock to lock and unclock the
This makes the Arduino Extremely Easy to use. Arduino TheArduino projectmakes it even easier to use microcontrollers as it gives you an open source compiler and simple IDE (Integrated Design Environment). It lets you program in C/C++ and upload programs very easily with the push of a button....
Make connections as shown. Make sure you connect Ground Pin of RFID reader to Ground Pin of Arduino. I am using the SoftwareSerial Library of Arduino which enables digital pins to be used in serial communication. I have used pin 9 as the Rx of Arduino. (You can also use the hardware R...
The RC522 has an operating voltage between 2.5V to 3.3V and hence is normally powered by 3.3V and should be used with 3.3V communication lines. But, the communication pins of this module are 5V tolerant and hence it can be used with 5V microcontrollers also like Arduino without any additio...
Why use Arduino? Simplicity Besides the main microcontroller chip, a microcontroller will require many different parts to work. What Arduino did was take away all the essential components of a microcontroller and design it so that it is effortless to operate on a piece of Printed Circuit Board ...
After opening a subkey (don't forget true! as it give you permission to delete), we can use the autoshell in order to change any value in the following subkey.5- Hints to use registry with VB.netWe can count the values in a hiveMy.Computer.Registry.CurrentUser.ValueCount.ToStrin...
Next we need to give life to the two buttons. So when the “TurnOn_Button” will be clicked we will use the Bluetooth client function “Send1ByteNumber” to send a number to the Arduino Bluetooth module. In our case that’s the number 49 which corresponds to the cha...
Are you trying to use the UART bridge that connects the USB interface to a (virtual) Com-port on your PC? Then you need to use the SCB - based component and connect Tx and Rx to Port4_0 and _1 When using a direct connection from your Tx and Rx pins P0_5 and _4 you will nee...
RFID Module The generally used RFID module is RC522 which falls under High frequency Passive RFID system. It is mostly used with microcontrollers likeArduino,PIC,AVRand other microcontrollers that support communication protocols like SPI, IIC or USART. Its interface is simple and has readily built ...
If you have an understanding of what your hardware should do, what you would like to track, and what information to collect, consider prototyping on platforms such as Arduino or Raspberry Pi. We advise you not to invest in custom-made hardware from the beginning, but to test your idea firs...
