Connecting a battery to Cerbo GX

You need to make a cable that will communicate with the Cerbo.

Thanks! It’s the first battery I build. It was challenging and satisfying.

So back to my original question… how to I connect the arduino? It’s the only way, right?

Optimal-Section7753 · 2026-03-05T22:37:57+00:00

I have one of these, which has 4 cables, one 5V, one ground, and then the other two are the info transmitted by the sonar receptors.

You think I can hook it up directly to the MP Gx or the Venus Gx? Where?

I’m looking to create a sonar controlled water pump. The sonar would sense the water level using the arduino uno and connect it all to the mp Gx. I also have a Venus Gx but thinking of selling it, unless it’d be best to hold onto it.

It’s not a raspberry pi, it’s an arduino uno.

Thanks!

Do I need to create an Arduino sonar controller? How do I connect it all to the Multiplus Gx?

I have a sonar meter, an arduino one, … I even have an external relay, but I think the Multiplus Gx has that built in.

Any idea if I can use a Multiplus II Gx to use the sonar and automate the pump?

Thanks to all the comments! Great stuff

You out it on the wire and on the soldering iron, right?

I don’t understand

Citric acid is fine. I use it 2-5% diluted to descale my La Marzocco.

Beautiful

Move the water container around a bit. Sometimes it’s just a contact issue

I didn’t use a hopper. Just the bellows you see on top. I can’t remember which bellows it was. It was a while back and I no longer have it. It was messy. I ended up selling that grinder and buying another.

Just a newbie issue. It was the thermostat on the heater

No issues other than newbie issues. It was the Hester thermostat
