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...
If the card gets recognized, the Arduino sends a signal to the relay to unlock the solenoid door lock for 10 seconds, Later, it locks the door automatically. To make it more user-friendly, I decided to use a 16x2 I2C-based LCD display to show door status and to provide important feed...
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....
