So this should be a fairly easy thing to do but for some reason I cannot wrap my head around it. I have a GP2Y0D805 IR sensor that is constant high output and goes low when an object is detected. I am using this sensor to input a count signal into a 74HC192. How do I reverse the logic? I think I may be able to use two NPN transistors but cannot figure out how to connect it all. Is this correct or is there a better way?
Thank you for any help.
