Hi! I'm new at using Arduino. Currently, I'm working on a Wind Speed (Anemometer) project. In short form, the Arduino Uno R3 Board is reading the analog signal from the wind sensor. It worked fine before. But, now I'm having an issue. The Arduino reads random Analog input numbers even the wind sensor is not spinning. Can anyone help with my issue? Thanks in advance. God bless you all.
Hello, do yourself a favour and please read How to get the best out of this forum and modify your post accordingly (including code tags and necessary documentation for your ask).
Yes what was said by @J-M-L
but this will happen if the analogue input pin is not connected to anything. If you made it on a solder less bread board that will be the problem of a bad connection.
