This was my BTech degree Mini-Project during semester 5 and it is an electronic lock which can be unlocked from anywhere.

LCD Custom Design Generator (4 Char * 2 Line)

In this project, the Bosch BMP280 sensor is integrated with an STM32 microcontroller using bare-metal, low-level register-based firmware. Communication is handled via I2C and SPI protocols. The firmware captures sensor data and outputs it to a 16x2 LCD display, demonstrating effective real-time data acquisition and display.
