![]() ![]() We have two Arduinos in our I2C network, so we have two sets of sketches. To select a specific version, add after the library name, followed by the version that you want to install.įor example, the following file will install the latest versions of Servo and FastLED, as well as version 2.3.Wire.begin() // join I2C bus as the master Int stat_LED // status of LED: 1 = ON, 0 = OFFīyte value_pot // potentiometer position Unsigned long time_start // start time in milliseconds Open the Arduino IDE and upload the code below to the master Arduino: // Arduino master sketchīyte i2c_rcv // data received from I2C bus One is for the master Arduino, and the other is for the slave Arduino. But you can find this file useful if you want to install a specific version of a library. Normally, you don't need to edit this file yourself - the "Library Manager" does this for you. It is a simple text file that lists all of libraries installed in your project, one library per line. When you add libraries through the built-in "Library Manager", it will create a "libraries.txt" file in your project. ![]() Any user who creates a copy of the project will be able to use the library in the copied project. zip file.Īnyone who opens the project will be able to download the library from the Library manager. You will be able to see the library in the Library Mananger as a. After selecting a folder, Wokwi will zip its contents and upload it to the Wokwi build server. The selected folder should contain the source code for the library (.h and. To upload a custom library, click on the blue "+" button in the Arduino library manager and then click on "Upload a Library". Uploading custom libraries Ĭlub members can upload any Arduino library by selecting a folder from their computer. You can use this method to install any Arduino library from the Arduino Library Manager. "FastLED"), and then click on one of the library names in the list to add it. ![]() Type some text in the search box to search for a library (e.g. ![]() To add third-party libraries to your project, go to the "Library Manager" tab in the code editor, and press the blue "+" button. You'll see a autocomplete dropdown with #include suggestions for popular libraries.īy default, Wokwi compiles your code with the standard built-in Arduino libraries, such as Wire.h and SPI.h. To include a library, go to the code editor and type # on an empty line. ![]()
