Arduino Libraries

  1. Drag it to your Libraries Folder Open your sketchbook Libraries folder and drag the master folder from Downloads into it. Give it a Legal Name The IDE will not recognize folders with dashes in the name.
  2. SI4735 Arduino Library Features This library uses the I²C communication protocol and implements most of the functions offered by Si47XX (BROADCAST AM / FM / SW / LW RADIO RECEIVER) IC family from Silicon Labs. This library also has primitive functions that make it easier for you to implement commands that may not have been implemented yet.

Extract the ZIP file with all its folder structure in a temporary folder, then select the main folder, that should have the library name Copy it in the “libraries” folder inside your sketchbook. Start the Arduino Software (IDE), go to Sketch Include Library. Verify that the library you just added is available in the list.

Libraries are files written in C or C++ (.c, .cpp) which provide your sketches with extra functionality (e.g. the ability to control an LED matrix, or read an encoder, GSM, GPS, NRF24L01 etc.). Arduino software is kept flexible users can create there own library or add libraries for new devices.

Adding Library to Arduino

Step 1: Download your library zip file example Keypad.

Step 2: Unzip your library file. You will find files “Keypad.cpp”, “Keypad.h” and folder “examples” ina library name folder in our case Keypad. These three are essential parts of any library.

Note that library folder name should not start with numbers and space is not allowed in library folder name.

Step 3: Find your Arduino Installation Location. By right clicking on arduino shortcut icon. Click on Properties.

Step 4: You will see this screen and Click on Find Target

Arduino

Step 5: Locate “libraries” folder and open it

Step 6: Copy and paste your library in this folder in our example it is “Keypad”

Check that you have these files in example library “Keypad” folder

Step 7: Close Arduino IDE and reopen it to see the added library in Examples>>Keypad

Step 8: To use library you need to add it in your code using include command.
Example:
#include <Keypad.h>

Introduction

This tutorial will walk you through downloading, installing, and testing the Arduino software (also known as the Arduino IDE - short for Integrated Development Environment). Before you jump to the page for your operating system, make sure you've got all the right equipment.

Required Materials

  • A computer (Windows, Mac, or Linux)
  • An Arduino-compatible microcontroller (anything from this guide should work)
  • A USB A-to-B cable, or another appropriate way to connect your Arduino-compatible microcontroller to your computer (check out this USB buying guide if you're not sure which cable to get).

Suggested Reading

If you're new to Arduino in general, you want to check out this tutorial to familiarize yourself with everyone's favorite microcontroller platform.

How to install CH340 drivers (if you need them) on Windows, Mac OS X, and Linux.

If you're ready to get started, click on the link in the column on the left that matches up with your operating system, or you can jump to your operating system here.

Windows

This page will show you how to install and test the Arduino software with a Windows operating system (Windows 8, Windows 7, Vista, and XP).

  • Go to the Arduino download page and download the latest version of the Arduino software for Windows.
  • When the download is finished, un-zip it and open up the Arduino folder to confirm that yes, there are indeed some files and sub-folders inside. The file structure is important so don't be moving any files around unless you really know what you're doing.
  • Power up your Arduino by connecting your Arduino board to your computer with a USB cable (or FTDI connector if you're using an Arduino pro). You should see the an LED labed 'ON' light up. (this diagram shows the placement of the power LED on the UNO).

Drivers for Arduino Uno on Windows

Installing the Drivers for the Arduino Uno (from Arduino.cc)

  • Plug in your board and wait for Windows to begin it's driver installation process
  • After a few moments, the process will fail, despite its best efforts
  • Click on the Start Menu, and open up the Control Panel
  • While in the Control Panel, navigate to System and Security. Next, click on System
  • Once the System window is up, open the Device Manager
  • Look under Ports (COM & LPT). You should see an open port named 'Arduino UNO (COMxx)'. If there is no COM & LPT section, look under 'Other Devices' for 'Unknown Device'
  • Right click on the 'Arduino UNO (COMxx)' or 'Unknown Device' port and choose the 'Update Driver Software' option
  • Next, choose the 'Browse my computer for Driver software' option
  • Finally, navigate to and select the Uno's driver file, named 'ArduinoUNO.inf', located in the 'Drivers' folder of the Arduino Software download (not the 'FTDI USB Drivers' sub-directory). If you cannot see the .inf file, it is probably just hidden. You can select the 'drivers' folder with the 'search sub-folders' option selected instead.
  • Windows will finish up the driver installation from there

Linux

If you are a Linux user, you probably know that there are many different distribution 'flavors' of Linux out there. Unsurprisingly, installing Arduino is slightly different for many of these distributions. Luckily, the Arduino community has done an excellent job of providing instructions for most of the popular versions. Click on the link below that covers your flavor of Linux:

If the above directions did not work for you, or you don't see your distribution, try this catch-all guide.

You can go to the download page and download the latest version of Arduino for Linux (there are 32-bit and 64-bit versions available) when your system is properly set up.
