Arduino servo motor voltage.

Connect to the motor to the arduino as shown in the table below. However this torque varies with supply voltage. The servo motor used here has 17 kg cm torque this is its max. A motor a feedback circuit and most important a motor driver.

Connect the pwm signal pin of the servo motor with the 9the pin of arduino. 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. 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 potentiometer gives the analog input to the arduino that is stored in a variable to which it is mapped.

To control the servo motor we will be using the servo h library which comes pre installed with the arduino ide. Give 5v voltage supply to the servo motor via the voltage pin. This article is about interfacing a servo motor with arduino mega series board. Say at 4 8 5v it can give up to 14 15 kg cm.

Learn how to use potentiometer to control servo motor. The darkest or even black one is usually the ground. It just needs one power line one ground and one control pin. The detail instruction code wiring diagram video tutorial line by line code explanation are provided to help you quickly get started with arduino.

Torque rating at 6 6v. Servo brown wire ground pin arduino. Servo red wire 5v pin 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.

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. Image of arduino mega 2560. Using this mapping we can control the servo meter by adjusting the voltage of the potentiometer. A servo motor has everything built in.

Like this you can add as many servo motors as you want. Servo motor with arduino example code. The servo library supports up to 12 motors on most arduino boards and 48 on the arduino mega. This shaft can be positioned to specific angular positions by sending the servo a coded signal.

Do not try to rotate the servo motor by hand as you may damage. Servo yellow wire pwm 9 pin arduino. The servo motor has a female connector with three pins.
