4. Quick Start Guide¶
Step 1：Download_Arduino_IDE¶
Please click the card below to learn how to install Arduino IDE.
Installing the NANO R4 Development Board
① Click the development board icon on the left
② Type "uno r4" in the search bar
③ Select version 1.5.1. You can try other versions, but if uploading the code fails, switch back to 1.5.1. This tutorial's code was developed using version 1.5.1.
④ Click "INSTALL" to install
During the installation, a window will pop up-just click"Yes".
Step 3：Add library¶
Please click to 
download the library files we have provided.
Then click "File" -> "Preferences" -> "Setting" to check the sketchbook location. Place the libraries downloaded to the sketchbook location.
Upload Steps (Important) In all following lessons, the upload steps are the same. Please read carefully, and if you forget, you can return here and follow the steps: 1. Connect the Type-C upload port to your computer
After writing the code, select the board you want to upload to: "Tools"->"Board"->"Arduino UNO R4 Boards"->"Arduino Nano R4"
