What is servo sg90 motor

            Do you know about sg90 Servo motor

Servo motor SG90 is a tiny and lightweight server motor with high output power. It is used in an electronic devices and rotary or linear actuators that rotate and push parts of a machine with precision. It can rotate approximately 180 degrees (90 in each direction) and works just like the standard kinds but smaller. We can use any servo code, hardware or library to control these servos. It controlled by sending an electrical pulse of variable width, or pulse width modulation (PWM) through the control wire. There is a minimum pulse, and repetition rate.
