Intro to Inertial Sensors: From Taps to Gestures to Locations
Check out this great talk from Elecia White (of the embedded.fm podcast) about inertial sensors like accelerometers, magnetometers, and gyroscopes. This is a fantastic introduction to these sensors and how you can use them in a project to detect motion, orientation, and more. Elecia shows a great demo that lights up a cube depending on the output of each sensor so you can get an intuitive understanding of how a gyroscope output differs from an accelerometer output for example. You’ll even see some Adafruit boards like the 9-DOF IMU mentioned in the talk. Watch the full talk to learn more and find great resources for further study.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
