Starting my first robot, at age 73, called Orange Crush based on color paint I used. It's based on McCombs Ardubot II but it's going to be a living proof of concept until it falls over or the batteries won't run it. Right now I'm trying to use Radio Shack IR sensors as a remote control. Since these sensors will only cover 90-120 degrees, I plan to mount them in a triangle or square so one will always be pointing at the remote control.
I know virtually nothing about electronics. my problem is that I don't want to chew up pins monitering the sensors. If any of them get a hit, I want to get a notification that I have a hit and enough information that I can query the rignt one to get the command it received.
I could put an Adafruit Trinket out there to moniter them (I might just to play with master/slave computers) but there would seem to be an easier way to set a flag if the ORed results are not zero and in a byte transfer who set the flag to non-zero
Any help would be appreciated.
Thanks Ed
