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!

Controlling our LED strip with Python

Now that we have completed all of our electronics, we can test that we can control our DotStar LED strip using the Python programming language. Switch on your Pi Zero and connect to it via SSH as normal. First off, we will create a directory for all of our code for this chapter; type mkdir ~/WearableTech/Chapter6; and then move into the directory by typing cd ~/WearableTech/Chapter6.

We now need to enable the SPI interface on our Pi Zero. Start the Raspberry Pi Configuration tool by typing sudo raspi-config. From the menu that opens, select 5 Interfacing Options, and then in the sub menu select P4 SPI; then press tab to highlight Enable. Press Enter twice and then restart your Pi Zero by typing sudo reboot now.

Once your Pi Zero has rebooted, connect to it via SSH again, move into your newly created Chapter6 directory and then issue the following...
