The primary purpose of the Arduino board is to interface with sensors and devices ... The smaller Raspberry Pi Zero W consumes 0.5 watts of power when idle, and 1.75 watts when a monitor, keyboard ...

An Arduino is a microcontroller — a single board designed to control something and perform a specific task. Unlike a Raspberry Pi ... an accelerometer for detecting motion, or a Piezo sensor ...

which turns a Raspberry Pi Zero W into a neat little flight data recorder. The hardware has what you might expect from a flight recorder, including accelerometer, gyroscope, and pressure sensor.

After reading the accelerometer data with an Arduino, he’s able to capture all the sensor data and read it into a Python script. The next steps are to figure out a decent algorithm to integrate ...
