The MPU6050 motion sensor: a 3-axis accelerometer plus a 3-axis gyroscope with an onboard Digital Motion Processor. What it measures, where it is used, and an Arduino example to read it over I2C.
How ultrasonic sensors measure distance with sound, the parts of the common HC-SR04 module, and an Arduino example that classifies an object as Near, Far, or Too Far.
