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.
The Magnetic Imaging Tile uses an array of 64 hall effect sensors to convert magnetic fields to the visual spectrum. That's right! You can now see magnetic fields in real time! As is to be expected, there are caveats: the magnetic sensors used on the tile are some of the most sensitive on the market but you need to be within 1 to 2 centimeters of the tile to get a good image.
