For this project I am using the Arduino Mega 2560. Absolute Number of Steps Matter First, we should consider the number of steps needed for a full rotation of the motor shaft. In this prototype I used ...

Don't worry, the coding is simple enough to understand even without prior experience. An Arduino is a much better choice than a Raspberry Pi for tasks that require real-time input and responses.

He has the processor, of course. But everything else — clock, memory, and power — are from an Arduino Mega 2560. You could argue that’s two chips, but the board actually has several chips on it.

This project is by no means unique, lately we’ve covered controlling a church organ with MIDI, as well as a neat Arduino Orchestra, but the EnsembleBot is just so much more.

The magic lies in Arduino's Modulino nodes, which consist of various sensors and actuators that connect to the UNO R4 WiFi board. The Plug and Make Kit is a complete package to get started.
