Rancang Bangun Sistem Pengendali Kecepatan Putar Motor DC Dengan Perintah Suara Berbasis Arduino
AbstractToday's technological progress is growing very rapidly and is evidenced by the many innovations that have been created. One technology that can provide convenience for users is technology with voice recognition features. The spoken voice is recorded into the database and the system only recognizes the voice that has been recorded to the database. This feature of the voice recognition system can be used for various needs, such as security and equipment control. This feature can also be used to adjust the speed of the dc motor. Sound can be converted into digital data and can be used by the microcontroller to change the input voltage value for the dc motor using the PWM (pulse width modulation) method while at the same time adjusting the speed of the dc motor. This final project research aims to design and manufacture an equipment to control the rotational speed of a dc motor with voice commands. The design of the equipment uses an easy voice recognition sensor as a means of converting voice into digital data, an Arduino microcontroller as the main controller and a dc motor. The spoken words are designed and programmed to adjust the rotation speed as desired. The input voltage to regulate the speed of the dc motor is regulated by the microcontroller using the PWM method..
