Simple application to test if a piezo buzzer attached to pin 11 is working.
Install wiringPi and after that execute the following command to build the application:
cd buzzer/c/
gcc beep.c -o beep -lwiringPi -std=c99
Execute the following command to run the application:
sudo ./beep
Implementation of the Imperial March from Star Wars.
Install wiringPi and after that execute the following command to build the application:
cd buzzer/c/
gcc starwars.c -o starwars -lwiringPi -std=c99
Execute the following command to play the Imperial March:
sudo ./starwars
Install i2c tools:
sudo apt-get install i2c-tools
Enable i2c on Raspberry Pi with Raspian GNU/Linux distribution:
sudo raspi-config
Go to Advanced Options > A7 I2C and reboot the board
Verify that TSL2561 is detected on i2c address 39 on bus 1:
pi@raspberrypi:~ $ i2cdetect -y 1
