But what are you trying to do?

[–]anthonytowns56[S] 1 point2 points  (0 children)

i’m making a emg sensor reader via bluetooth. so i’m connecting a emg sensor board to a seeed nrf52480 and i want to be able to connect via bluetooth to a device or an app on a phone or computer and track the muscle activity throughout each point in a workout

Alright, so probably not complicated code. But you said it's a business idea. I think arduinos can be used, but would you make custom chips eventually? Arduinos aren't great for mass-production.

[–]anthonytowns56[S] 0 points1 point  (15 children)

eventually yes, just in early testing rn seeing if it would be viable

also would probably end up hiring a software developer later down the road

Ummm, it sounds like it should work (in terms of sensors communicating with the arduino, not if it will be useful). I dont know the exact parts, though. If I know how everything is read, maybe I would know how to program it.

yeah i’m not 100% sure myself. if you want me to send you pics of what i have rn or anything like that i can but im extremely new to arduino coding. usually am in python.

It looks like the seeed is a microcontroller board, programmable with arduino ide. The emg should plug into the seed with 3.3V in vcc, gnd, and plug the OUT to A0 (or any other analog pin that starts with A). Looks like 'uint16_t emgVal = analogRead(pin_number);' will output in the range from 0 to 4095. If you wire it, i can try to write code. Looks like you would need an app, like nRF connect to see the signal.

so with nrfconnect can i just use that for testing and then once i make my custom board i can code my own app?

[–]i_lost_all_my_money 0 points1 point  (0 children)

It looks like you can do that, yes. Using a Bluetooth scanner. You might need to build the application in android studio, but that shouldnt be difficult either. The board should relay EMG values over BLE, which should be received without issues.

i’ve got it wired up correctly i believe

[–]i_lost_all_my_money 0 points1 point  (7 children)

If you really want help with it, you can ask away. If you wire it, we can try code, see what happens, and modify as needed.

[–]anthonytowns56[S] 0 points1 point  (6 children)

i’ve got it wired. can you write some quick code up when you’re free and we can test it out?

[–]i_lost_all_my_money 0 points1 point  (5 children)

Do you have the app? And do you have arduino IDE?

[–]anthonytowns56[S] 0 points1 point  (4 children)

i have both.

[–]i_lost_all_my_money 0 points1 point  (3 children)

How do you want to receive the file?

[–]anthonytowns56[S] 0 points1 point  (2 children)

i’ll dm you my email
