Most common servos accept inputs from 1000 µs to 2000 µs, with 1500 µs corresponding to the center position. In practice, attached servos will adjust to their center positions, but perhaps not exactly. For a continuous-rotation servo, this will halt the servo’s motion.
ARDUINO SERVO EXAMPLE CODE
This sample code instructs a servo, connected to pin 9, to move to its center (90°) position. Myservo.write(90) // set servo to mid-point Arduino ServoWriteĪrduino’s servo library makes it easier to control servos with minimal code and complications. Arduino’s reference page for the ServoWrite command, which draws upon the servo library, offers the following example code: #include This might seem like beginner stuff, but until last week’s complications I have used Arduino’s servo library quite a few times with ease and assumed proficiency. The result – a better fundamental understanding of Arduino’s servo library, which I will try to share with you with this post. I described the account over at ToolGuyd ( An Oscilloscope, an Arduino Servo PWM Signal, and a Wild-Goose Chase) if you’re interested in the whole story. I wouldn’t call the experience a waste of time, but the experience occupied more of my time than I would have liked. Last Wednesday I spent most of the morning and part of the afternoon chasing a signal anomaly that, as it turns out, did not exist. Gift the gift of Make: Magazine this holiday season!
