Pca9698 driver

Step 1. Wiring Since the servo will use large amount of power, you need to provide this module with an independent power supply so as to ensure the servo will have adequate supply. Connect the independent power supply to the module as shown below:.

Step 2. Step 3. Save the code and click Upload. If you want to adjust the servo to rotate to a certain position, just try to modify the angle value in the code. Note: If you want to control 16 servos at the same time, you can open Servo. You can connect more than one control board 62 at most in serial to control more servos. Here we'll see how to connect two. The case is similar for connecting more than two.

There are pins at the two ends of the board and you can connect those at one end of a board and pins at the other end of another board, with 6 jumper wires, as shown below. Digital Oscilloscopes. Variable Supply. Digital Multimeter. Soldering iron kits. PCB small portable drill machines. I may make a commission if you buy the components through these links. I would appreciate your support in this way! The Arduino UNO has only 6 PWM pins that you can use for controlling servos but by adding one of these modules you can control up to 16 servos.

You can add multiple PCA modules to control even more servos but for this tutorial we will stick with just one also this module uses I2C communication.

So it only takes up two of your Arduino pins A4 and A5. OE — Output enable. Can be used to quickly disable all outputs. When this pin is low all pins are enabled. When the pin is high the outputs are disabled. There are two sets of control input pins on either side.

Both sides of the pins are identical! Use whichever side you like, you can also easily chain by connecting up two side-by-sides. There are 16 output ports. That is, for LEDs you probably want 1. I tried out the Adafruit library that most people use but found that the HCPA library is much easier to use and just as powerful. After you download it open up your Arduino IDE click on sketch and under the include library tab select add zip library navigate to where you downloaded the library to and select it.

Now that the library is installed click on file under the examples tab scroll down until you find hcpca and select the servo example:.

Defaults to OE on power-up. Output state change programmable on the Acknowledge or the STOP Command to update outputs byte-by-byte or all at the same time respectively.
