A PID controller is a versatile feedback mechanism in most of the industrial process due to its simplicity in structure and reliability, while the I-PD controller and PI-D are the variants of PID controllers which are particularly designed to reduce the influence of changes in the reference signal on controlled output. In this paper the one of the variants, I-PD is tuned with a modified approach of firefly algorithm. It has been implemented in Arduino (genuino UNO) board so that the controller can be used as a standalone controller with the processes where space as a constraint. Also the cost of the controller is very much reduced.The I-PD controller has been implemented in Arduino board for the first order, second order and higher order systems. In all the cases the response of Arduino is compared with the MATLAB response.
