Good afternoon, I am a student trying to create an autonomous hydroponic system like the one constructed in the youtube video. I am trying to connect the the EZO-PMP pumps up and I was wondering in the circuit diagram on the website it appears to have 4 connections but the cable that came with the pumps has 5. I am assuming the the blue INT wire is not used unless you are trying to setup the I2C mode for the device. Which 4 wires should I be using with the pump? I was also wondering the color mapping from the figure https://kylegabriel.com/projects/wp-content/uploads/sites/3/2020/03/Figure-Raspberry-Pi-Circuit-Diagram-05-scaled.jpg maps out to the wires in the EZO datasheet https://www.atlas-scientific.com/files/EZO_PMP_Datasheet.pdf thanks for any help you are able to offer.
Yes the blue one with your EZO PUMP is useless unless for the IC mode.
I do not connect it to the raspberry.
The white, green, red and black have to be connected.
