PENGATURAN KECEPATAN MOTOR DCMENGGUNAKAN PWM PADA PROTOTYPE ROBOT PEMBAWA BARANG KENDALI OTOMATIS

In prototype robot mover stuff reins otomatic needs controlling of motor dc speed using PWM (Pulse Witdh Modulation).Using this theory concept, speed of motor DC in this robot can increase speed control system of motor DC refer to decreasing speed of motor DC from full speed until stopped.Principle Reference that is using in decreasing of motor DC is between that robot dan barrier.In here, Measure tool for distance using ultrasonic signal , for this time, weitter used sharp GP as distance detector because sensitivity depend on other sensor. General Method that is used for motor DC speed control because endurance from disruption. Using PWM concept , controlling can be changed based on duty cycle. With change duty cycle 50% , 70% for example, we can combine with distance sensor dan line sensor. In here writter using photodioda sensor. When that sensor deteced black line it’s mean the value of resistance is high from photodioda. And when value of resistance is low, it’s mean that sensor read white value. Programmethat is used Arduino IDE and the board is Arduino Mega R2560
