Szukana fraza: [Abstrakt = "The objective of this article was to create an Arduino\-based electronic circuit for controlling the actuator of a shape memory material. To achieve this a circuit made of the following components was created\: Arduino UNO as the controller, dual full–bridge driver L297N to allow for regulation of the current passing through actuators spring, a relay module to cut–off current when regulation is not in progress, a current sensor ACS714LLCTR, ultrasonic ranging module HC – SR04, 1–wire temperature sensors DS18B20 and a 16x2 LCD display with converter to I2C communication. To power the hardware two power supply units were used\: 12 V 2 A to power the high\-current section and 9 V 2 A to power the Arduino board. Additionally a monostable switch and potentiometer were used to allow a human–machine interaction. The unit works as intended, but it can activate only low resistance actuators with resistance of a few ohms at most."]
