Overview
Servo Motor is a position (angle) servo driver, suitable for those control systems that need to change the angle continuously and maintain it.
There're three wires named GND (brown wire), VCC (red wire) and signal (yellow wire), which are ground wire, power wire and signal wire respectively.
By receiving the PWM signal, the servo enters the internal circuit to generate a bias voltage. Which triggers the motor to drive the potentiometer to move through the reduction gear.
When the voltage difference is 0, the motor stops, so as to achieve the effect of the servo. a specific PWM signal of the servo rotates to a specific angle correspondingly.
The control requires a 20ms pulse, the range of 0.5ms ~ 2.5ms can control the servo to rotate at 0 ~ 180 °.

DIY Fun Experiment
Arduino R3 controls the rotation of the servo; (connection diagram)
(code)
| #include <Servo.h>
Servo myservo; int pos = 0; void setup() { myservo.attach(9); } void loop(){ for (pos = 0; pos <= 180; pos += 1) { myservo.write(pos); delay(10); } for (pos = 180; pos >= 0; pos -= 1) { myservo.write(pos); delay(10); } } |
