Arduino Servo Motor Voltage

The darkest or even black one is usually the ground.

Arduino servo motor voltage.

Arduino servo motor a servo motor is a small device that has an output shaft. The servo motor used here has 17 kg cm torque this is its max. Learn how to use potentiometer to control servo motor. Image of servo motor.

This shaft can be positioned to specific angular positions by sending the servo a coded signal. Using this mapping we can control the servo meter by adjusting the voltage of the potentiometer. This article is about interfacing a servo motor with arduino mega series board. The servo motor has a female connector with three pins.

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. To control the servo motor we will be using the servo h library which comes pre installed with the arduino ide. 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. With the example code below you can control the exact position of the servo motor and it also includes code to sweep the servo arm back and forth automatically.

Like this you can add as many servo motors as you want. Servo motor with arduino example code. Following are the steps to connect a servo motor to the arduino. Servo yellow wire pwm 9 pin arduino.

Image of arduino mega 2560. The potentiometer gives the analog input to the arduino that is stored in a variable to which it is mapped. Torque rating at 6 6v. Connect the pwm signal pin of the servo motor with the 9the pin of arduino.

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. Servo brown wire ground pin arduino. Do not try to rotate the servo motor by hand as you may damage. A motor a feedback circuit and most important a motor driver.

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. However this torque varies with supply voltage. Give 5v voltage supply to the servo motor via the voltage pin.

The detail instruction code wiring diagram video tutorial line by line code explanation are provided to help you quickly get started with arduino. Say at 4 8 5v it can give up to 14 15 kg cm. Servo red wire 5v pin arduino.
