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!

Summary

In this chapter, you learned the necessary electronics to get our 3.3V Pi Zero to control 5V items, and also we have done some pretty tricky soldering to cut and rejoin our DotStar LED strip into a matrix.

We looked at ways of attaching electrical components to fabrics, which we have not used before and also had to think in a bit more detail about our portable power sources!

We have finished up with a truly portable, and even if I say so myself, quite a stunning new bag for our laptop to be transported around in!

In the next chapter, we are going to be learning about Python programming in a little more detail, as we make use of our Pi Zero to create our own pedometer.
