Connect 4 photointerrupter
Budget: $10 – $30 USD
The project consists in connecting nr 4 Photointerrupters (LTH-301-32), making sure that there is only one output pin for read by Arduino with the simple command digitalRead().
I need the electronical circuit and the PCB drawing
In the attached drawing there are 3 PCBs, two can support Photointerrupters, the third is dedicated to the components and the output connector.
I attach the Datasheet of the fork Photointerrupter.
