Hello Fernando,
Thanks for the super work you did.
I'm planning to start a new aquarium and I would like to manage it with ferduino.
At the moment I am in the test phase.
I'm testing the pcf8575, the temperature sensor circuit, the webcontrol, the level sensors and everything works very well. But I have a big doubt for the atlas scientific multiplexer.
The circuit you show is for the old pcb and the new one requires an extra pin (s1, s2, s3). Is it compatible with ferduino?
Congratulations again for the beautiful project
Regards
