Introduction

Note: This tutorial is for the MyoWare V2.0 Muscle Sensor and its ecosystem. If you are using the previous version, please refer to the older MyoWare Muscle Sensor V1 tutorial.

Using our muscles to control things is the way that most of us are accustomed to doing it. We push buttons, pull levers, move joysticks... but what if we could take the buttons, levers and joysticks out of the equation and control it with our muscles? The MyoWare 2.0 Muscle Sensor is an Arduino-compatible, all-in-one electromyography (EMG) sensor from Advancer Technologies that allows you to do just that! The MyoWare 2.0 Muscle Sensor has been redesigned from the ground up with a new, easy-to-use, compact design and upgraded with the latest and greatest chipset improving sensor performance and reliability. The innovative snap connector system eliminates the need to solder connections for the MyoWare 2.0 ecosystem. It's that easy: stick on a few electrodes (not included), read the output voltage and flex some muscles! In this tutorial, we will go over the features and related shields to connect the sensor to a muscle group.

Suggested Reading

If you aren’t familiar with the following concepts, we recommend checking out these tutorials before continuing. Depending on the Arduino development board that you are using, you may need to install drivers. The RedBoards use a different USB-to-serial converter compared to the Arduino Uno. Both the Arduino Uno and the RedBoard Plus use 5V for the logic levels.

Installing Board Definitions in the Arduino IDE

How do I install a custom Arduino board/core? It's easy! This tutorial will go over how to install an Arduino board definition using the Arduino Board Manager. We will also go over manually installing third-party cores, such as the board definitions required for many of the SparkFun development boards.
