About this item
【Small Size】It is tiny and lightweight with high output power. This servo can rotate approximately 180 degrees (90 in each direction) and works just like the standard kinds but smaller.
【Program for SG90】You can build the project like “Robot Arm/ Robot hand/ control the servo with potentiometer/ multi servo control” and so on.
【Hardware Connections】The SG90 has 3 wire interfaces in which the connections should be made as follows: Red wire-5V, Brown Wire-Ground, Yellow wire-digital pin 9.
What is SG 90 servo? It is tiny and lightweight with high output power. This servo can rotate approximately 180 degrees (90 in each direction) and works just like the standard kinds but smaller. You can use any servo code, hardware or library to control these servos. It comes with 3 horns (arms) and hardware. A Servo can be positioned to specific angular positions by sending the servo a coded signal. Servos, in general, require a lot of currents to operate since they have a motor inside. If you only need to control one small servo like this one you can connect it directly to Arduino. If you need to control two or more servos you need an external power supply or battery pack.
Specifications Operating voltage: 4.8 V ~6V Operating speed: 0.1 s/60 degree Stall torque: 1.8 kgf·cm Dead bandwidth: 10 µs Temperature range: 0 ºC – 55 ºC Weight: 9g
How to connect SG90 micro servo motor to Arduino Uno? The connection with Arduino is extremely easy. The servo has three leads. The brown one is the Ground so connect to it Arduino Ground. The red one is VCC which usually requires a voltage between four points eight to seven point two volts. So connect it to Arduino 5V. The last lead, the orange one is the control signal which needs to be a PWM signal with a periodic time of twenty milliseconds aka 50 Hertz and a duty cycle of one to two milliseconds so five to ten percent.
While an on time of one millisecond represents the -90° position of the motor shafts, one point five milliseconds represent 0° position and two milliseconds the plus 90° position. That means you can rotate the shaft a total of 180°. The SG90 servo has 3 wire interfaces in which the connections should be made as follows: Red wire-5V Brown wire-Ground Yellow wire-digital pin 9
Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
Found that servos were nicely packaged, received in good working shape. Seeking out good software that allows me to operate servos working at same time using Arduino. Suspect PWM is constricting usage at same time. Would be helpful if supplier had helpful hints for making software work with multiple unist at same time. Why I rated four stars. Accessories with servos were fine and worked well.
