In this issue, Maker G teaches friends to use Arduino to write a small program that uses a potentiometer to control the servo.

Generally speaking, if you use Arduino to control the servo, the servo will rotate according to the command you give until it reaches a specified position or angle, and then stop. If your servos stop for a while after a few turns, it could be due to the following reasons:

1.Programming issues: There may be a problem with your programming that causes the servo to stop after a few turns. Check the program to see if there are any logical errors or defects.

2.Power supply issues: The servo needs a stable power supply**, and if the power supply is not stable, it may cause the servo to stop after a few rotations. Check the power supply system to see if there are any voltage fluctuations or unstable power supplies.

3.Motor overheating: If the servo rotates continuously for too long, it may cause the motor to overheat, thus stopping the rotation. At this time, it is necessary to let the servo rest for a while to tease the car to avoid overheating and damaging the motor.

In short, if your servo stops for a while after a few turns, you need to check the above aspects to find out the problem and fix it.

The Arduino servo can rotate according to the number of rotations you set and pause when the rotation is complete. When using an Arduino servo, you need to use Arduino's servo library to implement the rotation of the servo and pass in the number of rotations of the servo as a parameter. Here's how it works:

First, declare a good servo object in the Arduino program and connect it to a specific digital IO port. Then, use the method to set the number of rotations of the servo; Finally, the delay() method is used to delay the rotation time of the servo, so as to keep the servo paused for a period of time. So, with the above steps, you can achieve the number of servo revolutions you want, and let the servo pause for a while.

This may be because you are using a delay function, which causes the program to pause for a period of time when executing to the delay function. During this time, the steering wheel stops turning.

If you want the servo to rotate continuously without pause, you can use a non-disruptive slim plug delay technique, such as using the millis() function to achieve the delay. In this way, your program can execute any other vertical and negative middle keys while delaying, so as to achieve the effect of non-pause.

There are two methods, 1. Arduino has its own library function to control the servo; 2. The servo is controlled by PWM, and after understanding the principle, it is not complicated to control. Please refer to the web link.

Control the servo with PWM.

PWM feet have 3, 5, 6, 9, 10, 11 six.

The servo is positively and negatively connected to the power supply, signal.

Wire one of these six PWM pins.

Arduino servo function rotation angle statement miscellaneous Category: Arduino briefly introduced the control of the servo last time, in order to facilitate everyone's understanding, today I will specifically analyze the servo function and its statements that come with Arduino, first introduce a few common statements of the servo function. 1. Attach (interface) - set the interface of the servo, only 9 or 10 interfaces can be used.

2. write (angle) - a statement used to set the rotation angle of the servo, and the angle range that can be set is 0° to 180°. 3. read()—a statement used to read the angle of the servo, which can be understood as reading the value in the last write() command. 4. attached()—determine whether the servo parameters have been sent to the interface where the rudder chawu starts.

5. detach()—detach the servo from its interface, which (9 or 10) can continue to be used as a PWM interface. Note: The above statements are written in the format of "servo variable name".
