Now our button should react to the button press, by writing Button pressed! to the console window. Did you notice anything particular? Try running it a bit more. Sometimes we get the printout message twice, don't we? This is because of the physical characteristics of the button. Internally, it has a lead that touches another lead when you press the button. But because of the physics involved, the leads will sometimes bounce slightly off each other and just enough for our program to register a difference in states.
05) Executing the code will make the LEDs usr0 and usr1 flash in order with some sleep time. You can stop the execution at any time by pressing the keys Ctrl + C (this is an escape sequence in Linux, any program should exit when you press this combination). The program is very basic and also quite crude. There is no input verification and it doesn't restore the system state after you exit. But it gives you an idea about the files that actually represent the hardware in the Linux kernel. We're sure you already know how to restore the LED states if you want to, so we can move ahead with more hardware examples.
Try it, you can reset the board by entering the command reboot in console. After this, we should be able to install the required packages. First install is pip, which is a handy Python package manager: root@beaglebone:~# opkg update && opkg install python-pip python-setuptools python-smbus This will take a minute or so, and once it finishes, you can install the Adafruit library: root@beaglebone:~# pip install Adafruit_BBIO Now we have the necessary library installed, and we can access it from the Python code.
