One of our easier and more powerful tutorials for detecting movement Adafruit’s Raspberry Pi Lesson 12. Sensing Movement has been updated. This guide now makes use of the adafruit-blinka circuitpython libraries which make talking to the PIR (motion sensor) and magnetic door switch as easy as possible. This guide works for both the early 20-pin Raspberry Pis (Rev 1 and Rev 2) as well as the current generation of 40-pin Pi’s (A, B, B+ and Zero). The code is straight forward, the component connections are minimal which makes this guide is an ideal place to start for someone just getting started with CircuitPython on a Raspberry Pi.
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.
