Wearable-Tech Projects with the Raspberry Pi Zero

By: Jon Witts

Overview of this book

With Wearable-Tech Projects with the Raspberry Pi Zero, you will begin with learning how to install the required software for your upcoming projects. You will also learn how to control electronic devices with the GPIOZero Python library. Next, you will be creating some stylish wearable-tech projects such as a motion-reactive LED cap and a Tweet-activated LED T-shirt. Toward the end of the book, you will be creating some useful health and fitness wearable-tech projects; these will help you monitor your heart rate, track your movements with GPS, and count your footsteps with your own pedometer. By the end of the book, you will have created a range of wearable-tech projects and learned enough about your Raspberry Pi Zero that you should be able to adapt these projects further or come up with your own creations!

Creating our final program

As our main program needs to run as soon as we switch our Pi Zero on, and we are also not likely to have a remote connection to it while using it, we need to adjust what we have done so far a little.

Firstly, our program will need to set up the socket connection between our GPS module and the gpsd daemon. Secondly, we will not be able to pass a keyboard interrupt to stop this program running, so we will need another method of doing so. The most logical method seems to make use of the shutdown button and LED we added in Chapter 2, Scrolling LED Badge.

Create a new Python file, open it in Nano by typing nano ~/WearableTech/Chapter9/gpsTracker.py, and then copy the following program into it:

#!/usr/bin/python

import gps
import simplekml
from gpiozero import Button, LED
from os import system
from time import sleep

# first create our gpsd socket
system("sudo...
