SEN0487: Get frequency value with Arduino Nano

userHead TDevelopTDevelop 2022-09-07 21:05:08 202 Views1 Replies



I bought a SEN0487 module connected an Arduino Nano.


I would like to read the frequency emitted by a buzzer.


Is it possibile get the frequency with the Nano version?


Do you have any code example?

Please read the analog voltage value directly and check the data.
