SG90 servo motor is a widely used servo motor in robotics and automation projects. It is a small and low-cost servo motor that provides precise control over angular position. In this article, we will provide a detailed SG90 wiring diagram along with FAQ and tables to help you understand how to wire SG90 servo motors in your projects.
What is SG90 Servo Motor?
SG90 is a micro servo motor that weighs only 9 grams and is small in size. It is a low-cost servo motor that provides precise control over angular position. SG90 servo motors are commonly used in robotics and automation projects because of their small size and high precision. SG90 servo motor has three wires, one for power, one for ground, and one for signal. The signal wire is used to control the angular position of the motor.
SG90 Wiring Diagram
The SG90 servo motor wiring diagram is simple and straightforward. It requires only three wires to be connected to the microcontroller or any other control unit. The following is the SG90 wiring diagram:
| Wire Color | Wire Function | Microcontroller Pin |
|---|---|---|
| Orange | Signal | PWM pin |
| Red | Vcc (Power) | +5V Power |
| Brown | GND (Ground) | GND |
Connect the orange wire to the PWM pin of the microcontroller or any other control unit. Connect the red wire to the +5V power, and connect the brown wire to the ground. Once connected, you must write the appropriate code to control the angular position of the motor through the signal wire.
FAQ
What is the function of the orange wire in SG90 servo motor?
The orange wire in the SG90 servo motor is used to control the angular position of the motor. It receives PWM signals from the microcontroller or any other control unit to move the motor shaft to a particular angular position.
What is the function of the red wire in SG90 servo motor?
The red wire in the SG90 servo motor is used to provide power to the motor. It should be connected to the +5V power supply of the microcontroller or any other control unit.
What is the function of the brown wire in SG90 servo motor?
The brown wire in the SG90 servo motor is used to provide ground connection. It should be connected to the GND pin of the microcontroller or any other control unit to complete the circuit.
Can I use SG90 servo motors with Arduino?
Yes, SG90 servo motors can be easily interfaced with Arduino using the Servo Library. You can use the SG90 wiring diagram mentioned above to connect the servo motor to the Arduino board.
What is the maximum angular position that SG90 servo motor can rotate?
The SG90 servo motor can rotate up to 180 degrees, which means it can move from 0 degrees to 180 degrees.
Conclusion
SG90 servo motor is a small and low-cost motor that provides precise control over angular position. The SG90 wiring diagram is simple and straightforward, requiring only three wires to be connected to the microcontroller or any other control unit. We hope this guide has helped you to understand how to wire SG90 servo motors in your projects with ease.
