The MyoWare LED Shield is designed to pair with the MyoWare Muscle Sensor. The blue 10-segment bar graph shows the magnitude of the measured signal. The more muscle activation measured, the higher up the board the lit LEDs will go. With this shield you will be provided with a visual representation of the signals provided by the MyoWare Muscle Sensor and an on-board lithium polymer (LiPo) power source.
This shield is likely to be the top board in a stack, so solder on some 1x3 male headers and plug into the sensor board. The power is supplied on the LED shield, but controlled by the power switch on the sensor. Once the stack is assembled, snap on some electrodes and stick the sensor on the target muscle.
The MyoWare Muscle Sensor to which this shield attaches is an Arduino-powered, all-in-one electromyography (EMG) sensor from Advancer Technologies. The MyoWare board acts by measuring the filtered and rectified electrical activity of a muscle, outputting 0-Vs Volts depending on the amount of activity in the selected muscle, where Vs signifies the voltage of the power source.
Note: The MyoWare Power Shield and the MyoWare LED Shield both provide power, but at slightly different voltages. Don't use both of these shields at the same time.
Note: This item may take longer to process due to battery installed in the equipment and therefore does not qualify for same-day shipping policy. Additionally, these batteries can not be shipped via Ground or Economy methods to Alaska or Hawaii. Sorry for any inconvenience this may cause.
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

For the curious (I know I was...).
Thank you, exactly what I was hoping to find in the comments.
Same here. Thanks!
What is the battery energy capacity????
How do you charge the LED battery?
The battery can be charged by connecting a micro USB cable to the board, and then connecting the cable to a computers USB port or a USB phone charger.
10 segment, or 8?
There are 10 segments.
