did not find fingerprint sensor :(

Hi,
I am currently working on R305 fingerprint modulei and Arduino R3.The problem is that i have uploaded my code even though i am getting that fingerprint sensor is not found.

Presumably there's a question implied there?

You need to give us three things to start...

  • Link to the R305 datasheet
  • Circuit schematic
  • Your code

Hi, I am presently working o the ultrasonic radar i want to detect the speed of the object coming towards the sensor. The circuit is ready and i need the code. Can anyone help me in the coding. Thanks in advance

Did you use R305 fingerprint succesfully? Is it enough good and stable?

I’m looking for a fingerprint sensor in order to build for my home automation. It need to be, of course, stable and compatible with Arduino and suitable price also. Dose anyone know any kind of that sensor, kindly let me know. Thank so much.
