Using selfie stick to take selfies
Hello everyone! Since we all know that selfies from smartphones have become very common these days, now we see selfie sticks as well which can be used to take picture of a big group. My question is how does a selfie stick work? Since it is so generic and it can be used by every smartphone, how does it actually communicate with the phone and make sure that the picture is taken at the right time? I mean if there is a button in the stick, what exactly does it do to tell the phone to capture a photo?
