Using third-party libraries

Demonstrate the methods of installing and importing libraries in three cases.

Install third-party libraries

The entire car case requires libraries such as Adafruit_NeoPixel, Adafruit_PWM_Servo_Driver_Library, TM1650, and IRremote.

xxxxxxxxxx
Install the software library yourself through the software manager, and the version must be consistent!

Add .zip library

Users need to know the location of the software library compressed package.

x
The third-party library compressed package is located in [Software Resources: Library]

You need to add the compressed package corresponding to each library in the picture, and the method is the same.

xxxxxxxxxx
After adding the library successfully, a success prompt will appear in the lower right corner of the Arduino IDE!

• View the installed libraries

Software Management Library

Use the library manager that comes with the software to install. This method requires confirmation that the installed version is consistent with the one we provide. Please do not upgrade at will to avoid program errors.

Adafruit NeoPixel

Search Adafruit NeoPixel in the management library and click Install.

xxxxxxxxxx
Adafruit_NeoPixel is a library for controlling RGB (red, green, and blue) LED strips.

Installation successful:

Adafruit PWM Servo Driver Library

Search for Adafruit PWM Servo Driver Library in the library manager and click Install.

xxxxxxxxxx
Adafruit PWM Servo Driver Library is a method for controlling PWM (pulse width modulation) servos and other motors, which changes the speed of the motor by controlling the pulse width of the voltage.

Installation successful:

IRremote

Search IRremote in the management library and click Install.

xxxxxxxxxx
The IRremote library is used to read the signal data sent by the infrared remote control.

TM1650

Search TM1650 in the management library and click Install.

xxxxxxxxxx
The TM1650 library is a software library used to communicate with the TM1650 chip.

Installation successful:

• View installed libraries

Import the library directly

Find the folder where the library is located and unzip the software library to the libraries directory.

Library location

Click Preference in the File directory

The path selected here is the library location:

Unzip all the software library packages we provide in this folder:

We need to restart the Arduino IDE to display the directly imported library.

Use third-party libraries

Include the header file corresponding to the library and you can use it.

xxxxxxxxxx
#include <TM1650.h>
#include <IRremote.hpp>
#include <Adafruit_NeoPixel.h>
#include <Adafruit_PWMServoDriver.h>

Notes

• If you are not sure about the new version update content, please do not update the library version

• Possible reasons for failure to import the library directly

Normal decompression method: the contents of the compressed package need to be in the next level directory

Wrong decompression method: the contents of the compressed package are in the next level directory, so it cannot be detected (there is an extra layer of IRremote-4.3.1 folder in the picture)
