The Raspberry Pi is an impressive platform for prototyping projects of any scale. From a simple blinking LED to a quadcopter, anything is possible with a Raspberry Pi – all you need is a little imagination and some extra components.
One of the most interesting areas of practical use is sensing the world around us, and using the data gathered in all sorts of ways. The world is full of data just waiting to be recorded and manipulated – for example, weather stations come with many different sensors to measure temperature, wind speed, humidity and pressure.
All this data can be stored and manipulated by a savvy hacker to produce graphs and tables that can be imported into other applications or projects. And of all the sensors on the market, the cheapest and most simple is the humble PIR, which is present in so many parts of everyday life.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
