I&#8217;m a supplier of servo motors, and I often get asked how to control these nifty little devices. So, I thought I&#8217;d put together this blog post to share some tips and tricks on controlling servo motors. Whether you&#8217;re a hobbyist working on a cool DIY project or an engineer looking to integrate servo motors into a professional system, this post is for you. <a href=\"https:\/\/www.zdservo.com\/servo-motor\/\">Servo Motor<\/a><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.zdservo.com\/uploads\/47703\/small\/precision-gear-motors91d1a.jpg\"><\/p>\n<h3>Understanding Servo Motors<\/h3>\n<p>Before we dive into how to control servo motors, let&#8217;s quickly go over what they are. A servo motor is a special type of motor that can be controlled to rotate to a specific angle. It&#8217;s made up of a motor, a control circuit, and a feedback mechanism. The feedback mechanism, usually a potentiometer, tells the control circuit the current position of the motor shaft. This way, the control circuit can adjust the motor&#8217;s rotation to ensure it reaches and stays at the desired angle.<\/p>\n<h3>Controlling a Servo Motor with an Arduino<\/h3>\n<p>One of the most popular ways to control a servo motor is by using an Arduino. Arduino is a great platform for beginners because it&#8217;s easy to use and has a large community of users who can offer help.<\/p>\n<h4>Step 1: Gather Your Materials<\/h4>\n<p>To control a servo motor with an Arduino, you&#8217;ll need the following:<\/p>\n<ul>\n<li>An Arduino board (I like using the Arduino Uno, but any board will work).<\/li>\n<li>A servo motor.<\/li>\n<li>Jumper wires.<\/li>\n<\/ul>\n<h4>Step 2: Connect the Servo Motor to the Arduino<\/h4>\n<p>Connecting the servo motor to the Arduino is pretty straightforward. Most servo motors have three wires: power (usually red), ground (usually black or brown), and signal (usually orange or yellow).<\/p>\n<ul>\n<li>Connect the power wire to the 5V pin on the Arduino.<\/li>\n<li>Connect the ground wire to the GND pin on the Arduino.<\/li>\n<li>Connect the signal wire to a digital pin on the Arduino (I usually use pin 9).<\/li>\n<\/ul>\n<h4>Step 3: Write the Code<\/h4>\n<p>Now, it&#8217;s time to write the code. Here&#8217;s a simple example that makes the servo motor rotate back and forth between 0 and 180 degrees:<\/p>\n<pre><code class=\"language-cpp\">#include &lt;Servo.h&gt;\n\nServo myServo;\nint servoPin = 9;\n\nvoid setup() {\n  myServo.attach(servoPin);\n}\n\nvoid loop() {\n  myServo.write(0);\n  delay(1000);\n  myServo.write(180);\n  delay(1000);\n}\n<\/code><\/pre>\n<p>Copy this code into the Arduino IDE, upload it to your Arduino board, and you should see the servo motor starting to move. Let&#8217;s break down what this code does:<\/p>\n<ul>\n<li><code>#include &lt;Servo.h&gt;<\/code>: This line includes the Servo library, which makes it easy to control servo motors with the Arduino.<\/li>\n<li><code>Servo myServo;<\/code>: This creates a new Servo object called <code>myServo<\/code>.<\/li>\n<li><code>myServo.attach(servoPin);<\/code>: This attaches the Servo object to the specified digital pin.<\/li>\n<li><code>myServo.write(0);<\/code> and <code>myServo.write(180);<\/code>: These lines tell the servo motor to rotate to 0 degrees and 180 degrees respectively.<\/li>\n<li><code>delay(1000);<\/code>: This adds a 1-second delay between each movement.<\/li>\n<\/ul>\n<h3>Controlling a Servo Motor with a Raspberry Pi<\/h3>\n<p>If you&#8217;re looking for a more powerful and flexible option, you can control a servo motor with a Raspberry Pi. The Raspberry Pi is a small single-board computer that can run a full operating system like Linux.<\/p>\n<h4>Step 1: Gather Your Materials<\/h4>\n<p>For this project, you&#8217;ll need:<\/p>\n<ul>\n<li>A Raspberry Pi (any model will work).<\/li>\n<li>A servo motor.<\/li>\n<li>A breadboard and jumper wires.<\/li>\n<li>A 5V power supply.<\/li>\n<\/ul>\n<h4>Step 2: Connect the Servo Motor to the Raspberry Pi<\/h4>\n<p>Unlike the Arduino, the Raspberry Pi&#8217;s GPIO pins can&#8217;t provide enough power to drive a servo motor directly. So, you&#8217;ll need to use an external power supply.<\/p>\n<ul>\n<li>Connect the ground wire of the servo motor to the ground of the power supply and a ground pin on the Raspberry Pi.<\/li>\n<li>Connect the power wire of the servo motor to the 5V output of the power supply.<\/li>\n<li>Connect the signal wire of the servo motor to a GPIO pin on the Raspberry Pi (I usually use GPIO 18).<\/li>\n<\/ul>\n<h4>Step 3: Write the Code<\/h4>\n<p>Here&#8217;s a simple Python script that makes the servo motor rotate back and forth:<\/p>\n<pre><code class=\"language-python\">import RPi.GPIO as GPIO\nimport time\n\nservoPin = 18\nGPIO.setmode(GPIO.BCM)\nGPIO.setup(servoPin, GPIO.OUT)\n\npwm = GPIO.PWM(servoPin, 50)\npwm.start(7.5)\n\ntry:\n    while True:\n        pwm.ChangeDutyCycle(2.5)\n        time.sleep(1)\n        pwm.ChangeDutyCycle(12.5)\n        time.sleep(1)\nexcept KeyboardInterrupt:\n    pwm.stop()\n    GPIO.cleanup()\n<\/code><\/pre>\n<p>This code uses the <code>RPi.GPIO<\/code> library to control the GPIO pins on the Raspberry Pi. Here&#8217;s what it does:<\/p>\n<ul>\n<li><code>GPIO.setmode(GPIO.BCM)<\/code>: This sets the GPIO numbering mode to BCM.<\/li>\n<li><code>GPIO.setup(servoPin, GPIO.OUT)<\/code>: This sets the specified GPIO pin as an output.<\/li>\n<li><code>pwm = GPIO.PWM(servoPin, 50)<\/code>: This creates a PWM (Pulse Width Modulation) instance with a frequency of 50Hz.<\/li>\n<li><code>pwm.start(7.5)<\/code>: This starts the PWM signal with a duty cycle of 7.5%, which corresponds to the middle position of the servo motor.<\/li>\n<li><code>pwm.ChangeDutyCycle(2.5)<\/code> and <code>pwm.ChangeDutyCycle(12.5)<\/code>: These lines change the duty cycle to 2.5% and 12.5% respectively, which make the servo motor rotate to the minimum and maximum positions.<\/li>\n<\/ul>\n<h3>Advanced Control Techniques<\/h3>\n<p>Once you&#8217;ve got the basics down, you can start exploring more advanced control techniques. Here are a few examples:<\/p>\n<h4>Position Control<\/h4>\n<p>Position control is all about making the servo motor rotate to a specific angle and stay there. You can use the feedback mechanism in the servo motor to continuously adjust the motor&#8217;s rotation to ensure it reaches and maintains the desired position.<\/p>\n<h4>Speed Control<\/h4>\n<p>Speed control involves adjusting the speed at which the servo motor rotates. You can do this by changing the rate at which the control signal is sent to the motor.<\/p>\n<h4>Torque Control<\/h4>\n<p>Torque control is used to control the amount of force the servo motor applies. This is useful in applications where you need the motor to exert a specific amount of force, such as in robotic arms.<\/p>\n<h3>Conclusion<\/h3>\n<p>Controlling a servo motor isn&#8217;t as difficult as it might seem at first.
