If you have read any of my posts so far you know I'm all about lights, cameras and RF
I have run out of pins on my on-going RF video project. I'm using the 08M chip. I have pin3 for input...good. I have to turn on an A/V transmitter...OK...one output pin. I need to send a tone to control my VCR operation on the receive end of things....fine....two pins. I need to turn on an IR LED array if it is needed...three...and I need 2 pins to know if it is needed...one to power the CDS and one to read it. OH yeah...camera too!...make that triple duty, I'll have to wire the camera and transmitter to power on at the same time as the CDS...
Question is: anyone see a problem using the same pin to turn on a mosfet to power my RF transmitter and camera and use the same pin to power the CDS??? I think I know, but I hate to keep re-doing stuff that don't work
