Summary of Arduino Servo Basic Code
This tutorial explains how to connect and control a servo motor using an Arduino. It provides wiring instructions, connecting the signal wire to digital pin 9, and includes C++ code to sweep the servo between 0, 90, and 180 degrees with one-second delays. The project demonstrates basic library usage for servo movement.
Parts used in the Arduino Servo Basic Project:
- Arduino
- Servo Motor
- Jumper wire
In arduino projects, you might add servo to your projects. This short tutorial, show you the basic how arduino and servo works together.
Instruction;
1) Connect all jumper wire as shown in diagram.
2) Connect the signal wire from servo to digital pin 9.

}
void loop(){

-
How do you connect the servo signal wire?
Connect the signal wire from the servo to digital pin 9. -
What is the first step in the instruction list?
Connect all jumper wires as shown in the diagram. -
Which library must be included in the code?
You must include the Servo.h library. -
Does the code make the servo move back and forth?
Yes, it sweeps the servo to 0, 90, 180, 90, and 0 degrees. -
How long does the code wait between movements?
The code waits for 1000 milliseconds (one second) between positions. -
How many wires are in a servo cable?
A servo cable has 3 wires. -
What happens if the servo cables are not connected properly?
The tutorial warns to ensure they are connected properly but does not specify the exact failure outcome.
