// # Product name: 10 Segment LED Bar Graph
// # Product SKU : FIT0188
// # Version     : 1.0

// # Description:
// # The sketch for using the 10 Segment LED Bar Graph with prototype shield

// # Connection:
// #        LED Bar positive pins -- Arduino digital pins through a 1K resistor
// #        LED Bar negative pins -- GND
