In this video, I showed how the servo works and connects to the Arduino.
Servo SG-90: ali.pub/4fi1ua
SG-90 with free shipping to Ukraine: ali.pub/4fi20p
Powerful Servo: ali.pub/4fi2lb
Arduino Nano: ali.pub/454su0
Connecting wires: ali.pub/454s27
From this video you will learn how the servo drive works and how to control it using the arduino microcontroller and the "Servo" library. The servomotor is used in various radio-controlled models, robots and CNC machines.
The servo motor has three wires for connection, two of them are used for power supply, and the third for supplying control pulses.
The servo drive consists of a DC motor, potentiometer, control board and gearbox. Using a gearbox, the motor rotates the output shaft, which in turn is connected to a potentiometer. The control unit reads the position of the potentiometer and, based on this information, decides where to turn the engine.
To control the servo drive, the Arduino development environment has a built-in Servo library. How to connect a servo to arduino and how to control it using the Servo library is shown in detail in this video.
