I want a digital IR counter that counts up to 3, 7 or 12 and plays a jingle when the goal number is reached - then resets itself to ZERO. Very simple - However, I have one more specific request to discuss I would be willing to pay for - Is there a way to have a sensor that when one object passes by it, it counts it on one digital counter - and when a different object passes through it, another digital counter counts it until the goal number is reached and it again, plays a song and both counters reset themselves. The second request is more complicated but I would like to know if that's possible with an RFID chip? The sensor and chip needs to be sensitive up to at least 8-12 inches away. Any questions, please contact me for any more project details.
It's possible. An RFID tag would be a bit complicated, but possible. Message me if you're interested in my bid.
