Accelerometers detect the magnitude and direction of acceleration. We can use them to measure acceleration or to turn on a device by tapping. In this video we will learn how to get the raw data from an accelerometer and print it to the serial monitor, then we will convert the raw data into a meters per second squared acceleration value. This is tutorial #42 in the Ultimate Guide to the Arduino, a complete video course on the Arduino microcontroller with 45 lessons that are designed to teach anyone how to master the Arduino at any skill level.
