The PID Toolboxduino

I’ve been working in a very involved projects lately, that it is why my blog have been suffering the lacks of posts. The idea is to have a PID controller in box, with different type of sensors and outputs to mainly control temperature, such as for sous vide in a rice cooker or croc pot, a smoker, a chocolate melting tank, anything that involves a precise temperature and electrical appliances.

Code is still messy but works, and it is bug free enough for me to post the project.

It features the following:

What you reckon, Do you like? would you pay for something like this? how much?

It started by digging a hole in the ground, like finding a treasure,  and carefully opening a bottle. It was the taste of sunshine, hinted with garlic, and bay leaves, transmuted into gold maybe?
