Wiring and voltage?

[hobojoe]

Hi @bway-dev ,

First, thanks for the idea to share your findings! Really helpful!

Could you share your wiring diagram? Did you use a resistor ? Which voltage did you use (5V ou 7V)?

Thanks

Hi hobojoe,
I'm not using it anymore. But as far as I remember I was using 5v and no resistors.

best regards

Internal resistance for YF-B10 is around 6kOhm (estimated). I am actually using it with atmega8a (3.3V). YF-B10 is suplied by 6.5V. My connection looks like:

9kohm resistor is to create voltage devider together with internal yf-b10 resistance. Therefore signal-high on int0 is actually around 3.1V which is enough for atmega to read as true
