Cool Nano Thermostat/Relay Project

Other Hardware Science and Measurement

Hi, I'm new here and wanted to share a cool project I just completed using my Arduino Nano.
I needed a way to keep my tank temperature between two values. I also needed to monitor the water temperature and compare it to two saved values (high limit & low limit) and actuate a relay when required.

The cool thing I found about this project is that you learn how to store temperature values for the high and low limit's into the EEPROM memory using a rotary encoder which I had no idea you could do so many things with only one actuator. I found the project on the Instructables website here in case anyone else wants to try it a as well.

Looking forward to learning and sharing on this site.

Nice project.
Did you build the portable version using the 3D files supplied in project?

Not yet, but I bring the 3D .stl file to a friend who has 3D printer and will be doing this soon
