Hi guys,
I have a question for the dosing module, called 5 bombs in just a ULN2003A from the data sheet it works with outputs, I can do it this way or I need to use a CI for each pump? I will use pumps 24v, another question, I need to feed the IC at pin 9?
Note the updated code already with the webserver module dosing errors with this, have not tried to solve but someone had problem?
Thank you!
