So I planned to create an alloy(?) hotplate, with resistors heating the thing up and controlled by my arduino to adjust/stop it automatically to keep food warm how I like (35°C max).
My problem is that I don't know what parts I will need to heat the hotplate and the best way to connect them; and if there are off the shelf resistors I can buy to achieve that goal.
I could reuse an existing hotplate but I am interested in something I can make myself from the ground up. Pride and stuffs.
Please, do not hesitate to ask if I didn't make a point clear.
