Arduino Servo Motor Voltage

This article is about interfacing a servo motor with arduino mega series board.

Arduino servo motor voltage.

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. Servo red wire 5v pin arduino. The potentiometer gives the analog input to the arduino that is stored in a variable to which it is mapped.

Connect to the motor to the arduino as shown in the table below. Servo motor with arduino example code. The darkest or even black one is usually the ground. 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 servo motor has everything built in. Give 5v voltage supply to the servo motor via the voltage pin. The best thing about a servo motor is that it can be connected directly to an arduino. Torque rating at 6 6v.

Using this mapping we can control the servo meter by adjusting the voltage of the potentiometer. Servo brown wire ground pin arduino. Arduino servo motor a servo motor is a small device that has an output shaft. Image of arduino mega 2560.

The servo motor used here has 17 kg cm torque this is its max. 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. Following are the steps to connect a servo motor to the arduino.

To control the servo motor we will be using the servo h library which comes pre installed with the arduino ide. However this torque varies with supply voltage. Say at 4 8 5v it can give up to 14 15 kg cm. Image of servo motor.

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

This shaft can be positioned to specific angular positions by sending the servo a coded signal. 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. 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.
