Hello guys
I am using Arduino nano and R305 Fingerprint sensor for my Project. But the problem is whenever I Upload the sketch into my Arduino, the fingerprint sensor stops getting working.
The kit which I am using was in working condition since 5 years but now its showing the problem I mentioned above.
Please suggest some solution.
Umm, if it stops working when you upload the code, then how do you know it is working when… you don't upload the code?
Debug. The sketch works in general? Or "nothing works"? Only the sensor not giving values? Maybe it is giving values but they are invalid?
U haven't changed the code and it worked before? Or u did change it?
What is the code?
Hello sweeta
Welcome to the worldbest forum.
We need some additional information.
Post your sketch, well formated, with well-tempered comments and in so called code tags "< code >" and a detailed circuit diagram to see how we can help.
Have a nice day and enjoy coding in C++.
