The need to have mechanisms and Technologies for the control of blood glucose levels is essential for people who have diabetes of any type. This disease still has no cure and is one of the main risk factors for cardiovascular diseases, such as heart attack, stroke, renal complications etc. The number of diabetic people in the world and in Brazil is alarming, in addition, Brazilians occupy the fourth place in the world ranking according to the last survey of the year, 2015, made by the International Diabetes Federation (IDF). Several studies has been conducted in order to obtain the best glycemic control of people with diabetes, one of the current forms of control under investigation is the development of an artificial pancreas. Through the union of three systems: glucose monitoring system, control algorithm and actuator system through an insulin infusion pump, it is possible to obtain efficient results in glycemic control as they already have studies. This work consists of developing a prototype of a low-cost and low-power embedded control system, Hardware in Loop (HIL), based on Arduino nano microcontroller, which can control the blood glucose level of a model of a type 1 diabetes patient, considering some perturbations and noises, using the Kalman filter as estimator. The results obtained with the implementation of the controller are analyzed in order to obtain a better performance.
