Hi,
I'm building a project robot vehicle. I need to differenciate between two LEDs blinking at two different frequencies. I need to do this in day light and from a considerable distance (about 20 meters). Any suggestions with regards to circuit design and/or devices to use? Path would be rough, therefore vehicle might have nose up or nose down while wheeling down. Appreciate all your help ! thanks
