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.

The code and more tech details are at

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

It features the following:
