I am completely new in this Arduino environment and I have a project that I’m gonna use waterproof ultrasonic sensor A02YYUW.
I am using Arduino Nano. When I upload the code below, I am getting the same values. Even the location of the sensoris constant, the values are same and I am getting the value of 0 cm mostly. I dont know how it is possible.
I did the same connections as sample project.
Could you please check and give me some support on my project?
Thanks in advance!
