Summary of Servomotor Explicado

00:00:00 - 00:10:00

In the video, we learn how to program an Arduino to control a servo using a potenciometer. We also learn how to create a scale to convert degrees to rotations, and how to use that scale to control the servo.

• 00:00:00 This is a servomotor, which is used in precision engineering applications. It uses internal electronics as well as mechanical parts to achieve it. A servomotor is typically seen as a contraption that converts electrical energy into mechanical energy. This type of motor is used to achieve precise control and can be connected to different accessories to achieve it. We control the position of a servomotor via a controller, which is why it is used in robotics automation and even remote vehicle direction. Generally, when we connect a motor controller to an AC power source, the motor will continuously rotate, but a servomotor is different. These motors do not rotate instantaneously; instead, they send signals that indicate the motor's exact position until it reaches its intended rotation. Normally, the motor will rotate only 180 degrees, but we can obtain values lower or higher than this type of circuit. These are closed circuit type motors, which provide the best control and are the most commonly used in robotics automation. In this video, we focus on the open circuit type motor. On the left side of the motor, we find a weight value. This does not represent the actual weight of the motor--it represents the torque the motor can apply. This small motor has a weight of 9 grams.
• 00:05:00 In this video, a servomotor is explained in detail. The servomotor has 259 revolutions per minute, with a Newton meter of torque. The output will be a revolution per minute, but 259 Newton meters of torque. This means that a torque under high speed has been turned into a torque at high speed. There are losses that the presenter has conveniently ignored for this example. In our previous video about servo motors, we explained how to calculate it. The motor for a CD player is connected to a small circuit board inside the unit. This board controls the rotation of the motor as well as the rotation's direction of rotation. It is also connected to the circuit board of a variable resistance. This is just a variable resistance. When the final engine rotates, the variable resistance changes and the circuit board reads this to know the position of the output. We're going to see how this works. But before we do that, where have you seen these motors used before, and why would you use them? Let us know in the comments. An electronic controller sends a signal to the servomotor which determines the position at which it should rotate. The controller can be something like an Arduino, or even a simple test board for servos. This is a
• 00:10:00 In this video, we learn how to program an Arduino to control a servo using a Potenciometer. First, we connect a 5-volt cable from the connector for ground to the negative side of the potenciometer. Next, we connect a 5-volt cable from the connector for power to the side of the potenciometer that has the terminal connected to the servomotor. Finally, we connect a cable from the terminal for power to the Arduino. The code we write in the Arduino's "pinMode" and "digitalWrite" functions tells the Arduino which terminal on the potenciometer is connected to the servomotor, and how much voltage to send to the servomotor. When the code is run, the servo will rotate until it is close to 0 volts, at which point the Arduino will know that it is in the correct position and will wait there until the servo moves again. We then learn how to program a Arduino to control a servo using a Potenciometer using a different circuit. In the second video, we learn how to create a scale to convert degrees to rotations, and how to use that scale to control the servo. Finally, we learn how to program a Arduino to control
