#ARDUINO SERVO PROJECT HOW TO#

In this tutorial I’ve shown how to install “Adafruit PCA9685 PWM Servo Driver” Arduino library, written by GitHub user “adafruit” to Arduino IDE, showing how to use the library functions with an example, while giving information about servo motors. Please double check the ground connections before running the code. Make sure your COM port and board setting is set right and power supply is on. You should see the servo motors running in sequence. Click “Verify” and then “Upload” in order to compile and execute your codes. Change the number to add or decrease the servo amount.Ħ.

Then add the code that proceeds to the next servos once a servo finishes It’s movement. Add a delay after each for loop to move each servo at different times. This will move the servos to clockwise direction, then to anti clockwise direction. In the void loop() function, add two for loops for driving each servo (one at a time) to maximum pulse length then to minimum pulse length. Set the servo refreshing rate to 60 Hz and add a slight delay for making sure that setup is done before any servo movement.ĥ. Then add the library function that stars the pulse width modulation (PWM) process.

#ARDUINO SERVO PROJECT SERIAL#

In the void setup() function, add the code that starts serial connection at 9600 baud rate. After setting the pulse lengths define a integer variable that we will use later for counting process.Ĥ. In this project I’ve used 100 for minimum, 2200 for maximum pulse length. Check your servo motors datasheets for optimal settings. Then define two variables for setting the servo motors minimum and maximum pulse lengths respectively. Add the command that initiates the library functions. To add our libraries to our sketch, type #include and #include at the beginning of the code.ģ. Open a new sketch and save it as "Multiple_Servo_Example”.Ģ.

#ARDUINO SERVO PROJECT DRIVER#

If you use this library in your other projects please tell in the comments.Ĭonnection diagram PCA9685 PWM Servo Driver module to Arduino and servos. Connections for servo motors to PCA9685 PWM Servo Driver module and Arduino is shown below. See the steps for how to do these actions. After that we’ll need to write and upload a code to control the servo motors to Arduino. In order to make this project first we need to wire the servo motors to the driver. In this example project, we will control multiple servo motors up to 16, with an Arduino microcontroller, and a PCA9685 PWM Servo Driver module. I'll show you step by step how to use the PCA9685 PWM Servo Driver library with a simple example. An Example Project Using Adafruit PCA9685 PWM Servo Driver Arduino Library Choose Adafruit-PWM-Servo-Driver-Library-master.zip file and click to Open. Then go to and select Sketch->Include Library->Add. Image Source (Royalty free) How to Install Adafruit PCA9685 PWM Servo Driver Library to Arduino IDEĢ. Servo motors are used commonly in hobby projects. Servo motors are used in hobby toys, elevators, robots, grippers, conveyor belts. Minimum pulse indicates servo motors 0 degree position, while maximum pulse indicates servo motors 180 degree position. In PWM there is a minimum pulse, a maximum pulse, and a repetition rate. This technique is named “Pulse Width Modulation” (PWM). As the motor rotates, so does the potentiometers knob, potentiometers resistance value changes, so the control circuit can regulate the movement, both in terms of speed and position.

A servo motors working principle could be described as this: DC motor attached to the gear mechanism rotates the potentiometers knob. Servo motors are made of a DC motor, potentiometer, a gear mechanism, and a control circuit. Servo motors are electric motors that are very efficient, compact and low cost. Tutorial Contents What is a Servo Motor and How It Works Servo motors (as much as you want, for the example project we’ll use 4), 3 Jumper cables for each servo, 5 Volt power supply.
