Overview / Usage

This project ordered for Java Jazz Festival 2017 music event in Jakarta, Indonesia as an aesthetic element to catch the crowds with an interactive light.
The light reflect any object in front the sensors.
The basic circuit is an analog Infrared Led and Infrared Phototransistor proximity circuit.
I use darlington transistor to drive big 10mm white led as an output.
I create a pcb that contains 4 set proximity circuits in one board.
Totally I build 700 PCBs for 8meter x 2meter interactive panel.
I use about 4400 IR Led, 4400 IR Phototransistor, 8800 SMD Transistors, 16000 resistors, 4400 10mm White Led.
