A tutorial on using the Arduino to control devices such as motors using PWM or pulse width modulation This makes it easy to control the motor right out of the box, through your Arduino using a PWM signal. Servo motors are top choice among hobbyists and are used extensively throughout the modern industry and particularly in robotics where they have proved highly adept at providing fine motor control for robotic limbs as well as mechanized prosthetics used by amputees The servo motor includes two main types: 180° servo motor and 360° servo motor. In fact, most of the people understand implicitly servo motor to be 180° servo motor.. 360° servo motor is similar to DC motor, except for no hardware driver is required The PWM outputs generated on pins 5 and 6 will have higher-than-expected duty cycles. This is because of interactions with the millis() and delay() functions, which share the same internal timer used to generate those PWM outputs. This will be noticed mostly on low duty-cycle settings (e.g. 0 - 10) and may result in a value of 0 not fully turning off the output on pins 5 and 6 PWM pulse can be generated using Arduino and L298 Enable Pin is used to get that PWM pulse and then it controls the motor speed accordingly. Before going into the further details I would like to tell you about the concept of PWM for controlling DC motor. Moreover, you can download the complete Arduino code for DC Motor Speed Control using.
