THE SG90 SERVO MOTOR WITH AN ARDUINO
Hi guys, today, I will show you how to use a servo motor with an Arduino. This tutorial is ideal for beginners because it is easy and it gives them the foundation to build interesting projects like robots for which servos are commonly used. Servo motors are high torque motors which are commonly used in robotics and several other applications due to the fact that it’s easy to control their rotation. Servo motors have a geared output shaft which can be electrically controlled to turn one (1) degree at a time. For the sake of control, unlike normal DC motors, servo motors usually have an additional pin asides the two power pins ( Vcc and GND ) which is the signal pin. The signal pin is used to control the servo motor, turning its shaft to any desired angle. For this tutorial, we will be using the popular SG90 servo motor and our goal will be to rotate the servo motor from one end to the other. Servo’s have high current requirement so when using more than one servo motor with the Arduino, ...
