Arduino Servo Motor Voltage
A voltage divider potential divider are resistors in a series circuit that scale the output voltage to a particular ratio of the input voltage applied.
Arduino servo motor voltage. If you will use high voltage battery and you want give power to arduino with same power source you need to put a 7805 voltage regulator in and make a parallel circuit for that too. The servo library supports up to 12 motors on most arduino boards and 48 on the arduino mega. A servo motor has everything built in. Torque rating at 6 6v.
However this torque varies with supply voltage. The potentiometer gives the analog input to the arduino that is stored in a variable to which it is mapped. This shaft can be positioned to specific angular positions by sending the servo a coded signal. Learn how to use potentiometer to control servo motor.

Following are the steps to connect a servo motor to the arduino. The servo motor has a female connector with three pins. Arduino servo motor a servo motor is a small device that has an output shaft. The darkest or even black one is usually the ground.
The best thing about a servo motor is that it can be connected directly to an arduino. On boards other than the mega use of the library disables analogwrite pwm functionality on pins 9 and 10 whether or not there is a servo on those pins. This article is about interfacing a servo motor with arduino mega series board. Servo brown wire ground pin arduino.
Servo yellow wire pwm 9 pin arduino. The servo motor used here has 17 kg cm torque this is its max. Connect the pwm signal pin of the servo motor with the 9the pin of arduino. It just needs one power line one ground and one control pin.
Like this you can add as many servo motors as you want. To control the servo motor we will be using the servo h library which comes pre installed with the arduino ide. Using this mapping we can control the servo meter by adjusting the voltage of the potentiometer. Say at 4 8 5v it can give up to 14 15 kg cm.
Servo red wire 5v pin arduino. Connect to the motor to the arduino as shown in the table below. Image of arduino mega 2560.
