Blinking Measures

How can I measure a person's blinks using and Arduino?

With or without delay?

(sorry - Forum joke.)

Are you asking what sensors might be available?

spend some time with google

google is your friend when it comes to basic research

With or without delay?


Better damn well be without delay! Otherwise we’d be sitting around a lot more.

… hmmm. My firmware might be using delay.

Chessy, try putting light detectors on glasses, that look at a person’s eyes from the side. See if you can detect a change at the blink. Google is good - and you will get lots of ideas from it, but nothing beats physical experimentation!
