Abstract

To maintain the physical condition in order to remain healthy, we need to maintain our body by sport. There are many kinds of sports, likes swimming, jogging, soccer, basketball, Volly and etc. Meanwhile, in this final project aims to make sports equipment for a bicep curl. This tool will be utilizing the elasticity of the spring nature. The spring will be assembled on a steel framework which will also be connected by a sensor. Sensors used in this final task of the potentiometer. Working principle of this device are as follows: the sensor input of the potentiometer, which will convert the force that arises when a person is pushing the tool, so the potensiometer is pushing too, so that the pressure generated by such person will produce a voltage analog signal in accordance with the powers. Analog signals from the sensor signal, will be converted into digital signals by ADC, will then be processed by the data microkontroller force is needed. The results will be displayed on the LCD so that it can be seen directly how much force is needed. Values obtained from the experiments statutes spring (k) of 89,4 N / m and the value of the average error of 7.85% experiment.
