Arduino PID Controller ShieldThis easy-to-make shield converts your Arduino into a full-featured PID controller.
Arduino Board Step 2 of 15
The PID controller shield has been designed and tested using an Arduino Uno R3. It should also work on the Arduino Mega and other 5V boards with standard dimensions. The firmware does not fit on the Arduino Leonardo due to the larger size of the bootloader. The shield is not suitable for low voltage models like the Arduino Due.
