In this project, we connect a Grove Accelerometer and a Buzzer to the Raspberry Pi to determine if the Accelerometer is tilted or not. You might use this project to detect and record motion, or to control a robot. We use a Grove switch to turn the entire circuit on and off.
This project is a simple example to demonstrate how to use multiple Grove Sensors with GrovePi and Raspberry Pi in your Projects. Most of the parts used in this project are available in the GrovePi Starter Kit but you’ll have to get the accelerometer separately.
Tilt Buzzer Connections
Hardware Required
- Raspberry Pi
- GrovePi
- Grove Accelerometer
- Grove Buzzer
- Grove Switch
- Grove Connection wires
Hardware Setup: Connecting the Raspberry Pi accelerometer
Connect the Buzzer to port D2, the switch to port D4 and the Accelerometer to any of the I2C ports.
Now power on the Raspberry Pi.
Software: Running the Program
Run the tilt buzzer program in GrovePi/Projects/tilt_buzzer folder:
sudo python tilt_buzzer.py
If you turn the switch on and tilt the accelerometer in the X direction, the buzzer will start making a sound.
