This repository demonstrates how to implement motion detection using a PIR sensor with an LED and serial output across multiple platforms like Arduino Uno, ESP32, Raspberry Pi Pico, and STM32 Nucleo.

Methodology Output pin of the PIR sensor is connected to P3.5 of the microcontroller. Data pins (D0 to D7) of the LCD module are connected to Port 0 of the microcontroller. Each pin of Port 0 is ...
