Depending on the amount of data to process, file generation may take longer.

If it takes too long to generate, you can limit the data by, for example, reducing the range of years.

Abstract

PL W artykule przedstawiono opracowany system do sterowania siłownikiem wykonanym z materiału wykazującego pamięć kształtu. Omówiono zjawisko pamięci kształtu, proces nadawania elementowi wykonawczemu wymaganych właściwości, budowę aktuatorów oraz właściwości Nitinol’u. Opisano system złożony z elementu wykonawczego, układu pomiarowego prądu, temperatury i położenia, układu silnoprądowego oraz mikrokontrolera.

EN 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.
