Hopefully, these tutorials can offer some inspiration on how to use the Raspberry Pi in new ways outside of the usual monitor+keyboard interface. The following tutorial shows you how to set up a Raspberry Pi as an access point. ThingSpeak) on the Pi that collects and stores data from other WiFi devices. This could be useful if you want, for example, to run an IoT service (e.g. If you do not have access to a WiFi network, but want students to be able to connect to and send data to the Raspberry Pi, you can configure the Pi as a standalone WiFi access point. This allows you to control the Raspberry Pi like you would if it had a monitor, but from another computer! To see how to accomplish this, refer to the VNC tutorial on.

With X, you can install a VNC server to broadcast the standard Raspbian interface over the network to another computer. Instead of Raspbian Lite, you can also install regular Raspbian, if you want to have the X server (graphical user interface that shows you windows, icons, etc.) running. To get you started, we have a tutorial that walks you through setting up the Pi as a headless device using a variety of methods. are all possibilities, even without a monitor. Running Python scripts, writing C programs, hosting websites, etc. This will limit you to just the command line on the Pi, but many of the commands and programming languages are still available to you. One of the easiest is to use the Raspberry Pi as a "headless" computer, which means interacting with it without the aforementioned accessories.

This can easily double or triple the cost to get up and running.įortunately, there are a few ways around needing a full setup. One downside of the Raspberry Pi, however, is that it requires users to purchase a separate monitor, keyboard and mouse to use it. Teachers are able to use it as an inexpensive platform for teaching a variety of coding concepts. I want to collect data from a website on a regular basis (using Raspberry Pi & Python). You can check the status of your service using : sudo systemctl status myscript.The Raspberry Pi is a fantastic little computer that enjoys widespread popularity in the classroom. Reboot the Pi and your custom service should run : sudo reboot Step 4 – Check status of your service Now the unit file has been defined we can tell systemd to start it during the boot sequence : sudo systemctl daemon-reload The permission on the unit file needs to be set to 644 : sudo chmod 644 /lib/systemd/system/rvice Step 3 – Configure systemd In order to store the script’s text output in a log file you can change the ExecStart line to : ExecStart=/usr/bin/python /home/pi/myscript.py > /home/pi/myscript.log 2>&1 Note that the paths are absolute and fully define the location of Python as well as the location of our Python script. For my GPIO based scripts the default type of “simple” didn’t work. The “Type” is set to “idle” ensures the ExecStart command is only run when everything else has loaded. The “ExecStart” parameter is used to specify the command we want to run. This defines a new service called “My Script Service” and we are requesting that it is launched once the multi-user environment is available. You can save and exit the nano editor using, then.

Next we will create a configuration file (aka a unit file) that tells systemd what we want it to do and when : sudo nano /lib/systemd/system/rviceĮxecStart=/usr/bin/python /home/pi/myscript.py Obviously your script can be called something else but keep an eye on where it is referenced in the commands and text below. My example script was stored in the /home/pi directory and named “myscript.py”. My goal was just to get it to launch one of my scripts with the minimum of fuss and without having to do too much typing I didn’t understand. As a result it seems to have plenty of enemies but you can read all about the controversy on the systemd Wikipedia page.

systemd is a software suite for central management and configuration of a Linux system and aims to replace other popular tools that previously fulfilled this role. I decided to use “systemd” as this seems to the recommended way of launching custom features and lots of Linux distributions are adopting it.

The /home/pi directory is mounted and read for use.

The point at which your Python script is run in the startup sequence is vital if your script relies on any system features being available at that point in time. How much of an issue this is depends on what your Python script is trying to do and what resources it needs. It appears that the Raspbian boot sequence has changed and these processes run at different points in that sequence. With the latest release of Raspbian I started to struggle to autorun Python scripts on bootup using Cron or rc.local.
