+What is electromyography?
36
+
37
+Measuring muscle activation via electric potential, referred to as electromyography (EMG), has
38
+traditionally been used for medical research and diagnosis of neuromuscular disorders. However,
39
+with the advent of ever shrinking yet more powerful microcontrollers and integrated circuits, EMG
40
+circuits and sensors have found their way into prosthetics, robotics and other control systems.

+1) Connect the power supply (two 9V batteries)
47
+- a. Connect the positive terminal of the first 9V battery to the +Vs pin on your sensor.
48
+- b. Connect the negative terminal of the first 9V battery to the positive terminal of the  second 9V battery. Then connect to the GND pin on your sensor.
49
+- c. Connect the negative terminal of the second 9V battery to the –Vs pin of your sensor.
50

51
+2) Connect the electrodes
52
+- a. After determining which muscle group you want to target (e.g. bicep, forearm, calf),  clean the skin thoroughly.
53
+- b. Place one electrode in the middle of the muscle body, connect this electrode to the  RED Cable’s snap connector.
54
+- c. Place a second electrode at one end of the muscle body, connect this electrode to  the Blue Cable’s snap connector. 
55
+- d. Place a third electrode on a bony or non‐muscular part of your body near the  targeted muscle, connect this electrode to the Black Cable’s snap connector.
56
+
57
+3) Connect to a Microcontroller (e.g. Arduino)
58
+- a. Connect the SIG pin of your sensor to an analog pin on the Arduino (e.g. A0)
59
+- b. Connect the GND pin of your sensor to a GND pin on the Arduino.
