I had a project to measure Heart rate and SPO2 using Max30102 and Oled 128x64 pixels to display and graphic the info. I also want to send data from device to thingspeak but when I send data using AT command it's always crashed. Anyone can review for me???
Link github: anproa31/nanoPulse (github.com)
Hardware:
Arduino Uno R3
Push Button
Max30102
Oled 0.96" 128x64
ESP-01 Module
Software:
Thingspeak
Arduino IDE
I moved your topic to an appropriate forum category @bui_an_123.

Probably something wrong in your code....
Can u tell me what's the problem in my code
Is that the code you haven't posted? Tricky.
Can you think how you can alter that?
I want to graphic the Heart rate so the code is so difficult to read but it's not relevant to send data to ThingSpeak
So how is it going to get from what ever processor you have, this is still a secret, into your ThingSpeak?
We only know what you tell us and so far you are telling us nothing. It is almost like you don't want to understand your project, you just want it solved. But be realistic, if you do not cooperate with us then answers will stop coming.
In my code, I get the data SPO2 and beatAvg and put it into the API write link. Example
https://api.thingspeak.com/update?api_key=API_KEY&field1=beatAvg. My ESP-01 processor
L106 32-bit RISC microprocessor and on Arduino is Atmega328. That's what I know. Sr I am just a newbie and maybe I don't understand what u talk
So wasting my time here if you can't understand me.
You need a basic understanding of what you are doing before asking for help. I would recommend that you build up your experience by trying and understanding the basic examples found in the menu File -> examples -> Basic 0 to 9. Study them and make changes to see the effect of those changes.
That is a curve ball. Don't know much about that one. But is is a 3V3 processor so it will not produce the 5V signals I believe you use for a thingspeak. Just use your Atmega328, although that tells me nothing about what Arduino it actually is, it is just the processor type.
Also that link just takes me to a page with a single 0 on it, so not very helpful.
No point in writing any more as you are not ready to ask for help here.
EDIT:- Oh it is a Arduino Uno
