The RFID reader communicates with the Arduino through the SPI protocol and different Arduino boards have different SPI pins. To test if the RFID reader is working properly or not, upload the “dumpinfo ...
This project is an Arduino-based password entry system that uses a 4x4 keypad for input and a 16x2 I2C LCD display to show messages. The system allows users to input a password, which is then ...
The ARDUINO IDE associated with the ARDUINO board uses specific numbering, assigning numbers from 0 to 19 to digital pins 0 to 13 and numbers A0 to A5 to analog pins. GCBasic directly manipulates the ...
An RFID-based attendance system transforms the tedious task of manual attendance tracking into an automated, error-free process. What makes this project particularly exciting is how a few inexpensive ...
The I2C (Inter-Integrated Circuit) bus is a synchronous serial communication protocol that allows multiple electronic components (sensors, displays, memories, etc.) to be connected within the same ...
Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...
