Similar for servo motor connected at pin #6, you can move the lever along Y axis. You can also hold the servo actuator at a position, if you hold the joystick level at a particular position. PCA9685 outputs = 12-bit = 4096 steps // 2.5% of 20ms = 0.5ms 12.5% of 20ms = 2.5ms // 2.5% of 4096 = 102 steps 12.The two servo motors are controlled by one joystick when you move the joystick along the X axis the servo connected at pin #7 moves Clockwise and Anti-clock wise depending on the lever position.

Servo Motor Control using Arduino and PCA9685 Driver For controlling this servo driver we will use the PCA9685 library which can be downloaded from GitHub. Now let’s take a look at the Arduino code.

You can get the components needed for this example from the links below: It has a built in clock so it can drive 16 servos free running, or independently of Arduino. This is a 16-Channel 12-bit PWM and servo driver which communicates with Arduino using the I2C bus. There’s also another way of controlling servos with Arduino, and that’s using the PCA9685 servo driver. Of course, we can set any servo to move to any position, at any time.Īs an example you can also check my Arduino Ant Hexapod Robot project where I used an Arduino MEGA board to control 22 servo motors. So, we just have to create objects from the Servo class for each servo motor, and define to which Arduino pin is connected.

Here’s an example code for controlling multiple servos: /*Ĭontrolling multiple servo motors with Arduino On top of that, controlling multiple servo motors with Arduino is as easy as controlling just a single one. The Arduino servo library supports controlling of up to 12 servos at the same time with most the Arduino boards, and 48 servos using the Arduino Mega board. See Also DIY Arduino Robot Arm wiht Smartphone Control Controlling Multiple Servo Motors with Arduino Well that’s because this isn’t the original TowerPro MG996R servo, but a cheaper replica, which obviously has worse performance. The maximum current draw that I noticed was up to 0.63A at stall. I connected a multimeter in series with the servo to check the current draw. Pulses with 0.6ms duration corresponded to 0 degrees position, 1.45ms to 90 degrees and 2.3ms to 180 degrees. A pulse each 20ms digitalWrite(servoPin, HIGH) ĭelayMicroseconds( 1450) // Duration of the pusle in microseconds digitalWrite(servoPin, LOW) ĭelayMicroseconds( 18550) // 20ms - duration of the pusle // Pulses duration: 600 - 0deg 1450 - 90deg 2300 - 180degĪfter some testing I came up with the following values for the duration of the pulses that work with my servo.

Servo Motor Control - 50Hz Pulse Train Generator We just need to define the pin to which the servo is connect, define that pin as an output, and in the loop section generate pulses with the specific duration and frequency as we explained earlier. Now let’s take a look at the Arduino code for controlling the servo motor. See Also Arduino Brushless Motor Control Tutorial | ESC | BLDC Servo Motor Control Arduino Code
