Hello, I have doubt, I want to get the FFT of signals in arduino. I tried to use arduinofft library but have issues in plotting the frequencies present in my signal. any other methods?

Hi @Adhu ,
Can you specify the application ? also what was the issues when using the arduinofft lib?

Hi @salmanfaris,
I want to nullify the effect of noise in PPG signal acquisition. But before that I tried a example code which is present in the arduinofft library in GitHub, to check whether it is working or not?. I got an FFT plot but I think it is wrong. I don't know how to use that library. I'm beginner, so can you help me out?

@codelery said in Help needed: Arduino Wireless Notice Board project:
I am using the hardware serial (pin 0 and 1 on Arduino Uno)
As @rafitc99 mentioned, you need to expand the Serila buffer, in the hardware serial also the Arduino board package implements a 64-byte ring buffer for send and receive on the hardware serial messages. So you need to change that to 256 as per your message length.
