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.

Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm ...

Arduino uno (you can change the controller or move to esp32 also but just used hardware serial instate of software serial; GSm sheild (SIM900 -- 3G supported sim card) GPs Tracker (NY-06neo) Button; ...

Based on an ESP32 (using the Arduino stack) and SDCard for control, and a LiPo cell charged wirelessly, the build is rather tidy.

Arduino Uno - The World's Most ... The UNO R4 WiFi version comes with an Espressif ESP32-S3 module for Wi-Fi® and Bluetooth ... we are now launching the next-generation UNO R4 using our 5 V 32 ...

IO connections are in physically similar positions to Uno R3, and IO remains 5V. USB connector changed to Type-C. 6 – 24Vin (barrel jack – higher than Uno R3) 5Vin (USB-C) 14x digital GPIOs, D0-D13 ...
