Hi, i'm new here, new to arduino as well, got a question about IR sensors..
Is it possible to attach multiple IR sensors to just ONE pin? i would actually like all the sensors to work the same way.. and as there aren't enough pins on the Uno, i was wondering whether it's possible to attach an array of IR sensors, so that if any one of them (or all or multiples of them) is triggered, it would be detected?
Sure -- use sensors that make use of the I2C bus -- That is two wires. Some sensors like the Dallas Temperature sensors can use only one wire for data and two for power.
Some of the Sharp sensors can use the I2C bus.
But that has nothing to do with whether they "all work the same way".
Does that answer the question?
