Servo Controller with Voltage Display and Control Knob
- Brands China Code: SC-VD-CK
The RC servo motor is very popular in RC (Radio Control), and now it is widely used in robotics. Yet, as many of you may already know, standard RC Servo cannot rotate continuously, there is a limit of around 270º or 180º. Unlike a simple motor, which spins either forward or backward, a servo provides rather gradual and precise movement, either left or right. They’re the steering mechanism in any remote-controlled car you’ve ever played with.
But to make it work, power alone is not enough. You need a control signal as well, or it will not move. With this server controller, you can use its knob to adjust the position manually or use the servo to return to the middle position, showing the voltage of the power supply.
