This Halloween, developers can create spooky-themed projects using Python, Raspberry Pi, Arduino, and more. A Pumpkin Pi project combines a Raspberry Pi with custom code to control LED lights inside a carved-out pumpkin, while another project uses Spotify playlists to power Halloween sound effects. A dark theme for Terminal and other applications is also available, along with an impressive hardware project that incorporates an Arduino Uno, Raspberry Pi, and light strip LEDs. Additionally, there are resources available to help developers learn more programming through games like TwilioQuest 3, and a post highlighting unusual Python techniques that may be used in code but should not be.
