This is my first arduino program. Over the summer I was experimenting with fermented foods like yogurt and cooking methods like sous vide, both of which require temperature control. This was made in conjunction with the following:
- Arduino Uno
- DS18B20 digital temperature sensor
- LCD keypad shield
- A relay suitable for handling a crock pot or rice cooker
This does not use any PID algorithms unfortunately. Maybe in the future though. I was able to keep the temperature within a couple of degrees though! Quick info on use:
- Up/Down keys increase temperature by ½° F
- Right/Left keys increase/decrease temperature by 10° F
- Short hold of Select key toggles LCD (with backlight) on/off
Here's an album of an early prototype when I used it with kombucha.
Feel free to contact me if anyone out there happens to see this and has questions.
