Makerdoit 4pcs Micro Servo Motor SG90, for Robot Arm/Hand/Walking/Servo Door Lock

• 【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.
• 【Specifications】No Load Running Speed: 0.12 second/60 at 4.8V. Rotary Angle: 180°. Stall Torque (4.8V): 17.5oz /in (1kg/cm). Dead bandwidth: 7usec. Operating voltage: 4.8V~6V.
• 【Package Include】The package included 4pcs servo motor SG90, each SG90 come with one motor/ three servo arms and three screws.

<b>What is SG 90 servo? </b></br> It is tiny and lightweight with high output power. This servo can rotate approximately 180 degrees (90 in each direction) and </br>works just like the standard kinds but smaller. You can use any servo code, hardware or library to control these servos. </br>It comes with 3 horns (arms) and hardware. A Servo can be positioned to specific angular positions by sending the servo a coded signal. </br> 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 </br> like this one you can connect it directly to Arduino. </br>If you need to control two or more servos you need an external power supply or battery pack. </br></br> <b>Specifications</b></br> Operating voltage: 4.8 V ~6V</br> Operating speed: 0.1 s/60 degree</br> Stall torque: 1.8 kgf·cm</br> Dead bandwidth: 10 µs</br> Temperature range: 0 ºC - 55 ºC</br> Weight: 9g</br></br> <b>How to connect SG90 micro servo motor to Arduino Uno? </b></br> The connection with Arduino is extremely easy. The servo has three leads. The brown one is the Ground so connect to it Arduino Ground. </br>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. </br>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 </br>and a duty cycle of one to two milliseconds so five to ten percent. </br></br> While an on time of one millisecond represents the -90° position of the motor shafts, one point five milliseconds represent 0° position and </br>two milliseconds the plus 90° position. That means you can rotate the shaft a total of 180°. </br> The SG90 servo has 3 wire interfaces in which the connections should be made as follows: </br> Red wire-5V</br> Brown wire-Ground</br> Yellow wire-digital pin 9</br>
