In this chapter, you learned about the complexities of creating an accurate pedometer by taking a look at some of the maths involved in this process too. We also saw how to chain multiple I2C devices together on our Pi Zero. To be able to calibrate our pedometer program, you had to learn how to write data to a CSV file using Python, and then we briefly looked at how we can copy those files from our Pi Zero to our main computer using the SCP protocol.
Our final program combined the use of the Scroll pHAT HD from the Chapter 2, Scrolling LED Badge, with the reading of the accelerometer data that we first looked at in the Chapter 4, A Motion-Reactive LED Cap.
In our next chapter, we are going to look at how we can use our Pi Zero to create a simple heart rate monitor.
