Hi All,
This is my first post on the list.
I recently got a Umarim from PPZUAV.
I want to trigger a camera from one of the ADC using a 4N25V opto-coupler (
http://www.datasheetcatalog.org/datasheet/vishay/83530.pdf
)
Based on the opto-coupler specifications I calculated that I need a 42 Ohm resistor from the IO to the Anode. and connect the Cathode to the Umarim GND.
The result should be 3.3V pulse from IO = Opto-coupler Transistor Closed
Am I reading that right?
Regards,
Joseph
