Hi guys,
I am working on a device that starts recording video when the input is attached to ground (otherwise 0V).
I have designed the following. My idea here is that when the microprocessor first starts up, it sends 5 or 3.3 V so the switch is on all the time (microprocessor signal goes into pin 5). When I want the device to start recording, I simply just turn off the FET so the outputs (pins 2,3) are 0 and this tells the device to start recording.
Is there a more efficient way to do this?
Thanks
