well, i have decided to do my blinking eyes a different and easier way this time. i have this one question i have to ask you before i proceed. i want my eye mechanism to consist of a servo, a servo tester and a battery. as you can see, a servo tester has a knob to move it back and forth. what if i desoldered the knob off and bypassed it with an IR sensor? will that work? maybe it will because the servo tester has a 555 timer and handles PWM signals. the IR sensor is there to trigger the output signal. this is a much simpler way to make it work and i'll be glad if it did! it's also very cheap compared to what i spent on these 3 pack off branded nanos that i won't be using. the servo tester also has a built in sweeper mode that automatically moves the servos in a windsheild wiper motion. any help is appreciated and thanks for you help! i also like how this new idea calms my mind and makes me less frustrated with coding and faulty boards.
What is the purpose of the IR sensor?
like the knob, it triggers the output signal, just a different sensor is used. as for how the IR sensor would work, if you place your hand in front of it, the servo should move to 180 degrees. when you pull your hand away from it, the servo jumps back to 0 degrees.
What is the reason for putting your hand over an IR sensor instead of just using the knob?
well, i wanted to do a "hands free" version to blink my costume eyes. the IR sensor will be placed under my eyes, like where my lower eyelid is, and when i squint or blink, the IR sensor detects it as an obsticle and moves the servo 180 degrees. it's alot better when you can control the eyes with your eyes because you have both of your hands free to do almost anything, pick up objects, and do hand movements and even pose. it's better that way and it gives me less trouble to controll it.
That sounds super awesome!
Have you tested to verify that the IR sensor is able to detect this?
no but i am asking you to tell me if it's gonna work or not.
this board does simular. you can hook up any component to it, and will do exactly as i described! in the video of this board, he uses a microphone! the bad thing about this board is it can only accept up to 5 volts. how long would this thing last before the batteries die?

Why would I do that. The "DIY" in DIY projects stands for "do it yourself". So now is the time for you to start doing things for yourself!
From your other topic:
bopitlover12:
well, i have the servos and the IRs and the regular nanos (i bought them before i changed my mind) i started with, but no nano everys and battery packs.
I can see that you already have the IR sensors. So just wire one up, hold it next to your eye, then see if it can detect a blink or squint with anything close to reliability. You'll have a faster and better answer than anything you could hope for from a forum, and you'll have fun and learn at the same time.
i just want to know if it will work before i possibly waste money on it cause i'm not sure if it will work or not. do you have those materials laying around? IR sensor, servo, servo tester, battery?
this is a homemade servo tester but with buttons instead of a knob.
i have a good feeling this is gonna work out great! and these servo testers you can find for $99 cents to $5.00 each! i don't think it would hurt to try because i only need the servo testers. i already have the 2 servos and IR sensors and battery packs. what do you think?
you can replace the knob with any sensor you like and it will work as long as it has positive, negative and signal? or output?

No, but you don't need all that to determine whether it's feasible to detect a blink or squint with an IR sensor. You have everything you need to do that already. So do it!!!
i already told you i was not going to use Arduinos anymore for this project. i have now moved on to servo testers because it's easier and will not make me frustrated, and no components that would blow out.
“ will that work?”
NO
I don't understand the conversation going on here 
I suspect that Pert is egging him on to try out the idea and find it does not in fact work.
Mind you, we have no idea what an "IR sensor" is in this context, or which "servo tester" it is.
I have a servo tester but I don't think it has the "windscreen wiper" mode, so this must be something quite different.

O.k. but this is an Arduino forum so we're likely to have trouble helping you with some unidentified "servo tester". I mean I have a couple of servo testers but there's no way either of them will take instructions from an unidentified "IR sensor" even if that IR sensor could somehow identify a blink, which is also a bit doubtful.
You can't make a working project just by asking random questions. Either you start TESTING ideas to see if they really work or you give up.

Probably because it is so fragmented, across so many topics >:(
It is more interesting when you piece the fragments all together:
The beginning of the project two years ago; an Uno and a DC motor to blink the eyes:
https://forum.arduino.cc/index.php?topic=570822
Now on to a servo for blinking the eyes:
https://forum.arduino.cc/index.php?topic=574210
But constantly blinking the eyes will run down the batteries, so I need a power switch:
https://forum.arduino.cc/index.php?topic=576889
Now I want to use a Nano Every for each blinking eye:
https://forum.arduino.cc/index.php?topic=708617
Actually, I don't want to use the Nano Every because it might turn into a grenade:
https://forum.arduino.cc/index.php?topic=709280
And now the twists and turns of the last two years posting on the Arduino forum have resulted in this thread with the conclusion to not use any Arduino at all.
