This case is used to house an Arduino UNO, MAX6675 w/ k-type thermocouple, MOSFET IRF530, and HD44780 LCD. This was used as the PID controller for a heater.
The open design allows for easy access to the Arduino and components and can be used for any project. M3 screws are used to secure the components and the top to the base.
Included is a schematic of the wiring and code if you are interested in setting up a PID controller.
