There is a Proximity/Ambient Light Sensor IC (Si1143) with three LEDs on the back of D
ECA. This demonstration will show how to use this IC to measure the distance between D
ECA board and an object. The light from three Infrared Light diodes (DS1~DS3) impinge
on an object and reflect to Si1143 photodiode. Photodiode converts the brightness of three i
nfrared lights into three electricity values, pass the values to ADC IC to convert into digita
