In this example we will attach a servo motor and set the angle of the servo to 90 degrees. Return true if this servo is attached, otherwise false Returns current pulse width in microseconds for this servo (was read_us() in first release) Returns current pulse width as an angle between 0 and 180 degrees The available functions are provided in the table below:Īttach the given pin to the next free channel, sets pinMode, returns channel number or 0 if failureĪs above but also sets min and max values for writes There is a servo library which can be used to control the servo motor. The VVR (Variable voltage) should be close to 6V. Given below is the circuit diagram:Ī Servo pin has three wires (Order to be connected in evive, left to right)Ĭaution: Power evive using a 12V 2A power adapter for smooth functioning of servo motor.

In the following example, I will be showing you how to control servo through channel 1. Signal pin of servo 1 is connected to digital pin 44 and servo 2 is connected to digital pin 45. Controlling Servo using evive and Arduino IDEĮvive has two dedicated servo motor outputs pins. Hence if the range of motor angular position is from 0 to 180, then minimum pulse width corresponds to 0 and maximum pulse width corresponds to 180. Minimum pulse width is the shortest time for the pulse has been HIGH and maximum pulse width is the longest time for which the pulse is HIGH. For most of the servos, a certain range of PWM correspond to the range of angle servo can rotate. The refresh interval (the minimum time to refresh servos in microseconds) is 20000, which means that the servo is refreshing at a frequency of 50Hz. Servo is controlled on the concept of PWM (Pulse Width Modulation). It consists of a suitable motor coupled to a sensor for position feedback.

A servo motor is a rotary actuator that allows for precise control of angular position.
