PiMetric: Monitoring using a Raspberry Pi
PiMetric: Monitoring using a Raspberry Pi
About the Book
If you've heard about the Raspberry Pi you may know that it provides a fantastic method to learn about using a computer and to develop some skills that go beyond the basics.
What sort of things will we learn?
Good question!
- A bit about the Raspberry Pi
- A bit about the software language Python
- A bit about Linux and measuring 'stuff'
Is this book for you?
It's not written for experts. It's put together as a guide to get you started if you're unsure about how to make the first move with a Raspberry Pi.
If you like you can get straight to the code here on GitHub.
Why has the book been written?
Because writing things down is a great way to remember them.
Writing about how to do cool stuff with computers means that we're accumulating ways to help ourselves out when the going gets tricky. Making a book out of the information is a no-brainer since that way more people benefit from the process.
Enjoy.
So I hope you get something out of the book, please excuse the sometimes light-hearted conversational manner in which I approach the topic and enjoy the Raspberry Pi!
