Perhaps I don't necessarily need to use the same pins
Both the sensors you quote are using I2C. So they both use the same 2 pins (SDA, SCL) to communicate. You can put many I2C sensors on those same pins, they each have an address to know which sensor is receiving/sending data to the master (here, your arduino).
Look for a tutorial on I2C first.
Thanks I get it now
@berkseo Good question. The code seemed good at the time I wrote it, but I can't say that it was extensively tested. I may circle back to it at a future date, and if so, I'll take a closer look. Even with more than 500 downloads of the code, no one has posted any feedback on how well (or not) it has run. Also, I not sure how compatible the posted code is with newer releases of the mysensors library.
Hi @raulp, welcome to the MySensors community.
I don't understand what you are trying to do, but the MySensors getting started guide is available from the rocket icon at the top of the forum (https://www.mysensors.org/about )
Developer contribution guidelines are available at https://www.mysensors.org/download/contributing
Library documentation is available at https://www.mysensors.org/apidocs/index.html
@gohan said in Arduino Pro Mini Shield for RFM69(H)W:
If I remeber right that pin is used as input so the RFM69 is not receiving any 5v signal. In addition there are people claming they have the RFM69 module working on 5v on data pins and 3.3v on vcc, but I hardly suggest to do it.
thank you just what i thought .
about direct 5v on data...well... i seen a big red sign saying n :DONT do it! lol
Level converters are so cheap...that i ordered 5 or 10 thoguether with rfm69 board.
sorry about hijack this topic, i though i was on general discussion
