arduino

In short, I am looking to use a 1link cable from my Apex to run 24V to an Arduino and stepper motor controller (Sparkfun EasyDriver). Power itself shouldn't be an issue as the EasyDriver board can source up to 30 volts and will step that down to power the stepper motor as well as the 5v needed...

Hello arduino ppl out there! Selling cuz I'm not so patient anymore. Tried to setup and I gave up. Works fine, reads fine. You just need to write a code and calibrate. This means, condition = used (once for.. 30min). One single package with: 1) Industrial grade PH meter 0-14ph. BNC connector...

Hello, I would like to share my build and problems with reef-pi, hoping that someone can help me solving. First of all i will explain my setup : Raspberry pi 3 B+ running every function i need on reef pi. I have been trying using many function over the years but the basics I always used is Power...

In my pursuit to trigger feed and maintenance modes using a single push button, I have come across a few challenges. Sure I have a Profilux 4 controller which handles most of my pumps and such. And my plans include connecting some buttons to trigger the modes (likely something from Harry's...

Atlas Scientific Temperature and pH (double junction) probes with EZO pH and Temperature circuits. pH circuit has an isolated carrier board, temperature circuit does not. Comes with pH calibration solution. Arduino and Raspberry Pi ready. Can do pick-up in Portland area or ship for $10. P

As part of a cross-country move, I've ordered two JBJ 65 gallon AIO aquariums to be drop shipped to sunny Arizona, where I'll have an opportunity to set them up and let them run for a few weeks before I drive out with the inhabitants of my current tanks (one reef and one planted fresh water)...

This thread highlights my development of Opex (name pending). So I know there is already reef-pi and @Ranjib and team is doing some some great work on that, so I am by no means looking to compete with the amazing work they have done (as I have already learned quite a bit reading through that...

The Why: After much searching I have seen a lot of the raspberry Pi builds that have been shared around and are kept updated. But I haven't seen any up to date threads for arduino controllers. So I figure I would track my project as it goes and try to build something that is fairly modular. I'll...
