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.

"The M95 is connected to the Raspberry Pi (K5) via its USART, all communications are done using AT commands. Voltage divider R6/R7 adapts the TxD signal to the 3.3 V rated digital input level of the ...
