The Buzzer is a great way to indicate something is happening with your GrovePi or GoPiGo robot car! Program it to listen to noise with the Sound Sensor, or detect light with the Light Sensor, and alert you when there’s something you need to know! Or just program it to sound every time your favorite basketball team scores a point! Cable included.
The Grove - Loudness Sensor is designed to detect the sound of environment. Based on LM2904 amplifier and a built-in microphone, it amplifies and filters the high frequency signal that received from the microphone, and outputs a positive envelop.
The Line Follower attaches to your Raspberry Pi Robots and enables you to program it to follow a line. Program your GoPiGo to serve a drink across a room, and learn the basics of how automated warehouse or self-driving cars work!
