It is an ideal servo for beginners. It is also widely used in radio control projects because it works with most microcontrollers and platforms such as Arduino, PICs, Raspberry Pi, etc. It is also used in the RC world due to its weight, size, and torque.

It can rotate 360 degrees.

Its cables are identified by three colors:

  • Orange: PPM signal
  • Brown: GND (-)
  • Red: Power (+)

If you are going to use it with an Arduino board, it can be powered via USB for testing.

What is a servo?

A servo is an electromechanical device that has the ability to maintain a stable and controlled position. It consists of a motor, a feedback system (such as a potentiometer), and a set of gears. Servos are commonly used in applications that require precise control of position, such as modeling, robotics, and automatic control systems.

What does it mean for a servo to be SG90 9g Tower Pro 180?

  • SG90: Specific model of the servo.
  • 9g: Weight of the servo in grams.
  • Tower Pro: Manufacturer's brand.
  • 180º: Rotation range of the servo, in this case, it can rotate up to 180 degrees.

What are servos used for?

Servos are used to control precise movement in various applications, such as controlling the position of moving parts in models, robots, steering systems in RC vehicles, among others.

What can we learn from servos?

Working with servos allows you to learn fundamental concepts of control, feedback, angular position, and how to interact with electromechanical devices. They also provide a practical introduction to the world of robotics and automation.

Class Activity: "Simple Robotic Arm"


  • Micro servo SG90 9g Tower Pro 180
  • Wooden sticks (for building the arm)
  • Cardboard or material for building the base
  • Potentiometer or knob (to control the servo)
  • Jumper cables
  • Development board (e.g., Arduino)
  • Protoboard
  • Power supply for Arduino

Steps: Building the base:

  • Use cardboard or another material to build a sturdy base.
  • Attach the servo to the base in a stable manner.

Building the arm:

  • Use wooden sticks to build a simple arm that can be moved by the servo.


  • Connect the servo to the Arduino using jumper cables.
  • Connect the potentiometer to the Arduino.


  • Program the Arduino so that the servo responds to the movement of the potentiometer. You can use the Arduino IDE and write simple code that reads the position of the potentiometer and adjusts the position of the servo accordingly.

Testing and adjustments:

  • Power the system and test how the arm moves in response to the potentiometer's rotation.
  • Adjust the code as needed to achieve the desired behavior.

This activity will provide students with a practical introduction to servo control and allow them to experiment with concepts of movement and angular position. Additionally, it will promote the development of skills in programming and prototyping.
