Raspberry Pi
Raspberry Pi's are "single-board and modular computers or micro controllers, built on the Arm architecture, often running a Linux operating system."
To help out with Raspberry Pi projects at PPM, post your ideas and comments on our Slack #electronics channel.

- Pi Day, March 14th (3/14), is celebrated yearly often by eating pie, pizza, and/or reciting the digits of pi.
- It was started in 1988 by the Exploratorium museum in San Francisco: https://www.exploratorium.edu/pi
Tips
The Raspberry Pi was originally going be a computer that could only run the Python language.
(That is how it got the second half of its name.)
- 50 Raspberry Pi Hacks & Tips You Should Know
- Five Ways To Run a Program On Your Raspberry Pi At Startup
- Rotate the Raspberry Pi screen
- To find out which shell you're using, run the command
echo $SHELLorps $$ - List/check installed fonts
fc-list | grep "DejaVu Sans" - If the Pi 3 B+ seems slow or unresponsive, check the green light at the edge of the board for activity
- WolframMark Benchmark Results:
- Raspberry Pi 3 Model B+ (2017), 1400 MHz: 0.14
- Raspberry Pi 400, 1800 MHz: 0.23
- Raspberry Pi 4 Model B (2018), 2000 MHz: 0.24
- To find out which shell you're using, run the command
Shut down the Raspberry Pi properly:
(just pulling the plug could cause memory card corruption.)
- ☐ Use the graphical user interface (GUI), or
- ☐ Use the command:
sudo shutdown -h now
