The whole point of microcontrollers and physical computing is doing something with the data sensed. If you sense a temperature, if you sense motion, you act on it. However, There’s a bunch of science involved when you want to make things move, making sure you have enough power to move said object. The best explanation of the science of making things move is “Making Things Move DIY Mechanisms for Inventors, Hobbyists, and Artists” by Dustyn Roberts.
I’ve written about this book before, and I own it in paperback and kindle version, because it’s that important to Arduino and Raspberry Pi owners. If you want action, you need this book. It simplifies the “magic” of making your microcontroller make things move, in some cases, very large objects.
