Hello,
About two years ago I built a great little temperature controlled relay using an Arduino Uno, a DS18B20 sensor, and a mechanical relay. I use it to control my fridge in order to reach higher temps for fermenting and lagering beer. It works very good and the accuracy of the DS18B20 is very good.
However, I've always had to drag my laptop to the basement or garage and use the IDE if I want to make changes to the temperature setpoints.
I'm not very familiar with using a touchscreen with arduino. My question is, can one use a touchscreen or any other input method besides the IDE to make adjustments to the setpoints?
My initial thought was no, one would have to use the IDE to make programming changes. But a guy can find inexpensive 110V temp controllers on amazon or ebay and those use simple buttons to change setpoints. I could easily buy one of those and be done but I have several Uno's and all the other parts to make one myself if it can be done.
Any help is appreciated and thank you.
