Control robotic hand using MyoWare EMG Muscle Sensor

Simple tutorial for controlling robotic hand using MyoWare EMG Muscle Sensor:

It is easy to control robotic hand using MyroWare EMG muscle sensor & we have provided a step by step tutorial to achieve it.

Let's get started:

Connect MyoWare EMG sensor to any muscle. Then check its max & min values in the serial monitor. When muscle is released then values coming from EMG sensor will be minimum. As soon as you close the muscle, values will increase. You must try it & see how much strength you have in your muscles. The harder you press your muscle, the greater the values will be.

Also this tutorial describes how you can move a server motor after reading incoming data from EMG sensor. This can help you make a robotic hand & every finger is controlled by a servo motor. So you will have 5 servo motors & fingers of robotic hand close or open with opening & closing of your hand. First you need to connect EMG sensor to your forearm & then EMG sensor will send those values to your serial monitor. Thus arduino will send those values to servo motors which will close or open robotic hand.

In the same way you can connect MyoWare EMG sensor to other muscles like bicep, calf or head.

Steps required for connecting MyoWare EMG sensor to muscle, reading incoming data from muscle, & sending  this data to control a robotic hand:

Step 1: Connect MyoWare EMG sensor to muscle:

Clean the skin before connecting MyoWare EMG sensor. First electrode closest to wires of MyoWare should be attached to the middle of the muscle. The second electrode should be connected to the end of the muscle. The final electrode with the black wire must be connected to the end of the muscle. 

Step 2: Read MyoWare EMG sensor data:

Opening AnalogSerialRead

This sensor sends analog input data that is readable through an analog input of Arduino. You need to open File à Arduino à Examples à Basics à AnalogRealSerial to read data coming from MyoWare sensor.

Uploading AnalogSerialRead

Upload AnalogRealSerial code to Arduino board.

Opening Serial Monitor

Open serial monitor. When you flex your muscle, the values enhance & reduce when you release it.

Step 3: Control Robotic Hand:

You can connect a servo to Arduino. Source code for servo is available here. Upload the source code. 

Also connect 4 more servos if you want to control a robotic hand. Each servo can control 1 finger of the hand.
