Hello,
I need to build one project to detect muscular reaction speed bassed on optical or acoustic stimulous using electromyography device.
Can anyone guide me or share other projects like this with me?
Thank you.
BR!
You could start with just making a reaction time game using a button for input.
Then move up to the electro-whatever.
Can you program a simple game with LEDs, a buzzer or beeper and a pushbutton?

This is a simply solution....
I need something more complicated bassed on EMG.
I should generate an output (noise or a light) and check analog value from EMG interface. to calculate the time between output and analog values graph.
Noise should be in with different db, and also random, left or right. Same with lights.
I have some ideas but is very important for me to see some projects and analyse them to identify if i can use them or not.
Thank's for your reply.
I got that. You missed answering my question, so.
Do you currently have the programming skills that would go into making a simple reaction time game with LEDs, some kind of sound producing element and a pushbutton?

I have programming skills to do that.
I only need some project examples like:
- different and random db sound generating project's
- random outpus for some lights project's
- EMG project's
To be sure that my ideea will work and avoid spending money for test.
Thank you!
OK, I see, programming no problem for you!
Last questions:
Do you need accurate measurable sound levels and specific light stimuli as one might find on a high end medical/scientific device?
Or are you just wanting louder and quieter &c., more subjective criteria?
What is your budget for hardware?
You may find specific expertise here, but your issues are not Arduino or programming orientated. You may find more better help elsewhere.
Certainly an Arduino board could handle all the logic, it seems like it is more a matter of what exactly you hang off it.

Nop. Is a graduation project. Is enought to be a difference between them, more louder or quieter.
What is your budget for hardware?
I didn't think about that, i hope it didn''t will be more expensive than 150 euro.
Thank's
For the lights I recommend neopixels, so-called smart LEDs.
Very easy to work with, hellishly bright, colours &c.
For the sound, here's something that might be of interest, although you may want to use a small audio amplifier between the Arduino and the speaker.
So that's not eating much of you budget.
I have no experience with the muscle sensing part, but I would anticipate some need to figure out how to get a good signal that represents only the muscle activation, not motion from dodgy connectors to the subject.
The UNO or other cheap Arduino will have 10 bit a/d conversion which for a toy like this should suffice. You may need external signal conditioning to get a 0 - 5 volt (or whatever Vref you choice) signal constraint and ready to be converted.
It may have occurred to you, but just in case, it would make sense to build and test this in parts. I would start with a pushbutton as proxy for the ultimate sensor input as one step, make the simple game. Sseeing how your muscle sensing and conversion works just spitting out valuesis another step, and the combining of those working programs as the last.
Oh, step zero and zero and 1/2 would be working with the sound and light hardware.
Sounds like fun.
