This project uses an Arduino and an ADXL345 accelerometer for Free Fall Detection. When a large acceleration shift characteristic of a free fall is detected, a warning system is activated, which includes an OLED display with the words “Free Fall Detected!” and a buzzer. This system can find applications in safety monitoring and fall detection … Read more
In a world where technology meets everyday tasks, we designed a digital “Spirit Level” making use of the ESP32 microcontroller, an ADXL345 accelerometer, and an OLED display. This practical instrument measures roll and pitch angles in real time, making it ideal for builders, DIYers, and hobbyists. How this Spirit Level works? In this project, an … Read more
