Pi Day is finally here. The least imaginative celebrate by cooking pies, the academic indulge in a worldwide celebration of mathematics, and the stubborn insist that Pi Day doesn’t make sense because the equation is an infinite number and not 3.14. That last group never gets invited to any of the parties thrown by the first two. Oh, and if you think we’re joking: the first widespread celebration of Pi Day was in 1988, and in 2009 Congress supported the designation of March 14th as Pi Day. It’s a real holiday, not just a math joke.

As for us? We’re celebrating Pi Day with a bunch of deals on courses that will teach you to tinker with Raspberry Pi — a miniature computer that's a great practice ground for programming your own electronics, robotics, and Internet of Things experiments. You can even use it to teach Amazon Alexa to do crazy things.

Take an extra 14% off all these deals today with code 3POINT14.

If you’re brand new to the Raspberry World (and don't actually own a Raspberry Pi), this is the best place to start. The included 55 lectures and four hours of hands-on instruction will explain the underlying Alexa ecosystem, discuss Alexa skills, and prepare your Raspberry Pi for building voice-automated projects. With the information provided, you can prepare your Raspberry Pi for building voice-automated projects, learn how to use the Amazon Developer Portal, and even build a skill to control an LED. And of course, it comes with an actual Raspberry Pi and all the sensors and tools you need to get started.

Normally $448.98, you can buy the Complete Raspberry Pi 3B+ Starter Kit and Course for just $120.39 with code 3POINT14.

If you want to go a little beyond the basics, this training bundle is your best bet.
