About Si1143
Si1143 is a gesture sensor and can be controlled by using the I2C.
This can be detected from the shortest 1cm up to 200cm.
Si1143 emits three infrared LED that is mounted on a substrate, and detects the movement by measuring the reflected light from the external object.

About sample program
When you hold your hand on the upper of LED1 of Si1143, LED1 (red) of GR-PEACH lights up.
When you hold your hand on the upper of LED2 of Si1143, LED2 (green) of GR-PEACH lights up.
When you hold your hand on the upper of LED3 of Si1143, LED3 (blue) of GR-PEACH lights up.
When you approach your hand to LED of Si1143, level of the LED light will output a large value.
