Comparison Of Voltage Measurements on DC Gearbox Motor and PWM Voltage Based On Arduino Uno

In this research, a DC motor tested using the L298 driver which is controlled by Arduino as speed regulator and PWM method control signal generator for motor. This research has several stages, namely literature study, arduino-based dc design, Arduino-based production, testing, then analysis of results conclusions are drawn. Testing on Arduino-bas, ed was done with experiments, adjust setting pwm value in program listing section measuring output pin 9 Uno board. Then measurements were made right left side experiment carried out from 15 to 255 determine difference increase voltage condition The test show that initial moves when set = 45, 0.83 V, 1.53 1.75 V.
