#ARDUINO CODE HOW TO#

Let’s get started for this tutorial I will be using an Arduino Nano and I will be using two servos but when we get to the Arduino sketch I will show you how to add more.

#ARDUINO CODE DRIVER#

The first thing we need to do is connect our PCA9685 Servo Driver module to our Arduino board. That is, for LEDs you probably want 1.0 KHz but servos need 60 Hz – so you cannot use half for LEDs 1.0 KHz and half 60 Hz. Each PWM runs completely independently but they must all have the same PWM frequency. Each port has 3 pins: V+, GND and the PWM output.

Pulled low by default so it’s an optional pin! 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. When the pin is high the outputs are disabled. When this pin is low all pins are enabled. Can be used to quickly disable all outputs. So it only takes up two of your Arduino pins A4 and A5. You can add multiple PCA9685 modules to control even more servos but for this tutorial we will stick with just one also this module uses I2C communication. 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. I would appreciate your support in this way! PCA9685 Servo Driver: I may make a commission if you buy the components through these links. The only condition is that the main control chip supports I2C communication, which means enabling the communication between the chip and PCA9685 Servo Driver, so as to control multiple servos simultaneously. PCA9685 is a 16-Channel and 12-Bit PWM Servo Driver can help a lot when there are insufficient PWM output pins for the MCU in your project. In this article we will look at how you can control up to 16 servos with your Arduino board using a PCA9685 Servo Driver module. Thanks to the PWM PCA9685 Servo Driver which can control multiple Servos using only two wires, because it uses the I2C bus. There are times when we need to control more Servos then in a situation like this we will need more pwm pins. In the setup, the LCD is initiated with lcd.init() and the backlight is turned on with lcd.backlight().PCA9685 Servo Driver with Arduino- We often need to use Servos in our projects, without a servo driver we can control just a few servos because we have less number of pwm pins in Arduino Uno and Arduino Nano. Connect to LCD via I2C, default address 0x27 (A0-A2 not jumpered) You will need to change ‘lcd’ to the new name in the rest of the sketch. You can give it a different name if you want like ‘menu_display’. Note that we have called the display ‘lcd’. When using a 20×4 LCD, change this line to LiquidCrystal_I2C(0x27,20,4) This is where you will need to change the default address to the address you found earlier if it happens to be different. The next step is to create an LCD object with the LiquidCrystal_I2C class and specify the address and dimensions.įor this, we use the function LiquidCrystal_I2C(address, columns, rows). #include // Library for I2C communication The other library imports wire.h automatically. *When using the latest version of the LiquidCrystal_I2C library it is no longer needed to include the wire.h library in your sketch. In the rest of this tutorial, I will cover more of the built-in functions of this library. As mentioned earlier we need both the wire.h* and the LiquidCrystal_I2C library. First, the required libraries are included.
