PENGATURAN KECEPATAN PUTARAN MOTOR DC MENGGUNAKAN ARDUINO UNO R3 DENGAN TAMPILAN LCD

Abstract

The development of semiconductor technology is currently very rapid, especially in the field of power generation. In many power systems using electronic components that are generally used in a series of motor settings. The use of diodes, transistors and Silicon Controlled Rectifiers (SCRs) for motor control brings several advantages, such as fine (continuous) regulation, and very little power loss and fairly simple maintenance. This research aims to make it easier for us to regulate and measure DC motors, specifically to determine the rotation speed of more modern DC motors. In the design of tools, there are several parts namely the SCR function as a switch, while the Hardware (hardware) and software (software). The hardware also consists of several parts, namely the tool frame, Arduino Module, LCD and a pair of infrared shooters in the form of Infrared LEDs and a pair of sensor circuits as infrared receivers in the form of phototransistors and Regulator circuits. The software consists of a programming language that is the C programming language to run the Arduino module. The test results on this tool are determined based on the duty cycle because the duty cycle is directly proportional to the voltage while the results of the sensor and Techometer readings are specifically for the rotation of the DC Motor. If the duty cycle is 60%, the output voltage generated on the DC motor will be 16 Volts accompanied by a rotation of 580 Rpm for the techometer, while the rotation result of the sensor is 562 Rpm so that this value will be processed by Arduino then displayed on the LCD in the form of Rpm.
