The example code below lets you control a servo motor with a potentiometer.
Arduino servo motor control with potentiometer.
The potentiometer has three pins connect the outside pins to 5 v and gnd.
Because servo motors use feedback to determine the position of the shaft you can control that position very precisely.
It could be applied for ex.
Control the position of a rc hobby servo motor with your arduino and a potentiometer.
Servo motor control using a potentiometer knob we can use a potentiometer of any value between the 10k to 100k.
One side pin of potentiometer is connected with the ground another side pin is connected with 5v supply and the middle pin is connected with the analog input pin of arduino a0.
Servo motor with potentiometer arduino example code.
This instructurable cane be used in combination with my 4 servos 2 joysticks instructurable to control a robotic arm.
The middle pin of the potentiometer is connected to the analog pin a0 of the arduino.
This can damage the arduino mg996 instant high torque.
You can connect small servo motors directly to an arduino to control the shaft position very precisely.
Sg90 mini rc servo motors can be used.
Servo motors have three wires.
The power wire is typically red and should be connected to the 5v pin on the arduino or genuino board.
As a result s ervo motors are used to control the position of objects rotate objects move legs arms or hands of robots move sensors etc.
In this tutorial i will show arduino users how to control a continuous rotation servo or a normal servo.
Power ground and signal.
I suggest you use external power to the servo.
Analog input gets from the pot and according to this input the movement of servo change.
6 1 controlling the position of the servo motor we will use an analog input to control the servo motor this will be helpfull if you decide to make something with a pan tilt platform.
In this tutorial you are going to control the rotation of a servo with a potentiometer.
