Connecting the servo motor to the arduino.
Arduino servo motor controller.
Now let s see how to use an arduino to control a servo motor.
On the arduino due you can control up to 60 servos.
It makes careful use of timers.
The goal of this project is to intro.
Connect this to the arduino gnd.
You can also see the 3 wires that connect to the outside world.
The guts of a servo motor is shown in the following picture.
The servo expects one pulse every 20 ms.
Working of a servo motor.
For most servos a 1 ms pulse results in a zero degree rotation a 1 5 ms pulse results in a 90 degree rotation and a 2 ms pulse results in a 180 degree rotation.
The darkest or even black one is usually the ground.
Connect the power cable that in all standards should be red to 5v on the arduino.
In this tutorial an arduino board will be used to power and control a small servo motor.
Because servo motors use feedback to determine the position of the shaft you can control that position very precisely.
One is for power 5volts ground and the white wire is the control wire.
You can see the control circuitry the motor a set of gears and the case.
The basics and composition of an sg90 will be explored and the application of several servo codes and applications will be given for another type of servo motor the mg90s.
You can connect small servo motors directly to an arduino to control the shaft position very precisely.
The library can control 12 servos using only 1 timer.
As a result s ervo motors are used to control the position of objects rotate objects move legs arms or hands of robots move sensors etc.
This library can control a great number of servos.
