How to download and run the Code

Downloading Code to Your Raspberry Pi

Before downloading the code, please be aware that the example code has been tested ONLY on the latest version of Raspberry Pi OS. We offer two download methods:

If you’re not accessing your Raspberry Pi with a direct screen connection, consider utilizing remote access options. For detailed guidance, refer to the instructions in If You Have No Screen.

Method 1: Using Git Clone (Recommended)

1. Log into your Raspberry Pi, open Terminal, and navigate to the home directory (~). (You can also access the terminal using SSH.)

   cd ~
   

   

   Note

   Use the cd command to change directories. Here, ~/ denotes the home directory.

2. Clone the GitHub repository.

   git clone https://github.com/sunfounder/universal-maker-sensor-kit.git
   

   
   
   

3. Use File Manager to access the downloaded code files.

   

Method 2: Downloading Code Directly from GitHub

1. Open a web browser and go to https://github.com/sunfounder/universal-maker-sensor-kit, then click on the download button.

   

2. Once downloaded, locate the code file in File Manager > Downloads and unzip it into the /home/pi directory.

   

3. Navigate to the /home/pi directory to access the extracted code files.

   

Opening and Running Code

You can find the code for each project in its respective code section. Alternatively, you can locate the code in the provided code directory. For instance, in universal-maker-sensor-kit/raspberry_pi/, you will find Lesson 1’s code named 01_button_module.py.

There are two ways to run Python code below：

Method 1: Using Geany

1. Open the code file by double-clicking on it.

   

   Alternatively, right-click the file and select Open With….

   

   Choose Programming > Geany Programmer’s Editor and click OK.

   

   The code will be displayed for editing or review.

   

2. Click Run in the window and the following contents will appear.

   

3. To stop it from running, just click the X button in the top right corner to close it and you’ll return to the code. Alternatively, you can terminate the program by typing ctrl+c.

   

Method 2: Using Terminal

1. Log into your Raspberry Pi, open Terminal, and navigate to the home directory (~). (You can also access the terminal using SSH.)

   cd ~/universal-maker-sensor-kit/raspberry_pi/
   

   

   Note

   Use the cd command to navigate to the experiment’s code directory.

2. Execute the code:

   python3 Lesson_01_Button_Module/01_button_module.py
   

   

3. Upon running the code, the output will indicate whether the Button is pressed or not.

   

4. To edit the Lesson_01_Button_Module/01_button_module.py file, stop the code by pressing Ctrl + C. Then, open the file with:

   nano Lesson_01_Button_Module/01_button_module.py
   

   

5. nano is a text editor. This command opens nano Lesson_01_Button_Module/01_button_module.py for editing.

   

6. To exit nano, press Ctrl+X. If you’ve made changes, a prompt will ask whether to save them. Respond with Y (yes) to save or N (no) to discard. Press Enter to confirm and exit. Reopen the file with nano Lesson_01_Button_Module/nano 01_button_module.py to view your changes.
