Introduction
The RGB LED Strip Driver Shield allows an Arduino board to drive the RGB LED Strip. Through
control the 3 MOSFEET on the board,you can turn the RGB LED ON/OFF,and show colors
differently.
You can also control the RGB LED Strip Driver Shield by the IR remote controller.
The RGB LED Strip Driver Shield connects to an Arduino board using long wire-wrap headers which
extend through the shield. This keeps the pin layout intact and allows another shield to be stacked
on top.
Arduino uses digital PWM pins 9, 10, 11 to control the MOSFEET on the RGB LED Strip Driver
Shield. and the digital pin 4 is used to receive the IR signal.These pins cannot be used for general
i/o.
The shield have a fuse，it can limit the current.
