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!

Counting steps with Python

Power on your Pi Zero and connect to it via SSH as usual. If you have not followed the previous chapters in this book, then at this point, you may well need to enable the I2C protocol. Refer to the Chapter 2, Scrolling LED Badge, for details of how to do this.

With this covered, let's check whether we can talk to both devices on our I2C bus. Type the following into your Pi Zero:

sudo i2cdetect -y 1

All being well, you should see the following:

This lets us know that we have a device attached to the I2C bus on address 74 (our Scroll pHAT HD) and 53 (our ADXL345). If you cannot see both the devices on your I2C bus, shutdown your Pi Zero and check your soldering and cables. If we can see both the devices on the I2C bus, then we are ready to start writing some Python!
