Even it’s cheap, less than $5, don’t try to rotate the servo motor by hand because this may damage the motor. The Tower Pro SG90 servo is one of the cheapest servo motors that you can find on the market.
1 x TowerPro SG90 servo motor ( price ~$5).To control the TowerPro SG90 servo, you will need the following parts: Luckily, all the components are cheap and available worldwide. This is not a complex project, but we still need some parts. I’m just asking – why we need a servo motor? These servos are essential parts if we need to control the position of objects, rotate sensors, move arms and legs, drive wheels and tracks, and more. It’s a dedicated controller that makes the tiny things inside the servo to move with military precision.Ī feedback sensor, a controller, and a motor. But even so, there is something more sophisticated that controls all the stages of the servo motor. This sensor sounds the alarm when the motor is spinning. This very strict control of the angular position, velocity, and acceleration can’t be done without a sensor for position feedback. You control precisely the speed of the car and the direction. It’s like you’re at the steering wheel of your car.
