This project combines an Adafruit Trinket with a i2c accelerometer to create a USB seismograph. The output is sent as the keys A to Z to make it easy to integrate with environments like Scratch.
Adafruit Trinket – Mini Microcontroller – 5V Logic: Trinket may be small, but do not be fooled by its size! It’s a tiny microcontroller board, built around the Atmel ATtiny85, a little chip with a lot of power. We wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. Perfect for when you don’t want to give up your expensive dev-board and you aren’t willing to take apart the project you worked so hard to design. It’s our lowest-cost arduino-IDE programmable board!

Adafruit Triple-Axis Accelerometer – ±2/4/8g @ 14-bit – MMA8451: So many accelerometers and so little time! We’ve expanded our accelerometer selection even more with this high-precision and inexpensive MMA8451 Triple-Axis Accelerometer w/ 14-bit ADC. You can detect motion, tilt and basic orientation with a digital accelerometer – and the MMA8451 is a great accelerometer to start with. It has a wide usage range, from +-2g up to +-8g yet is easy to use with Arduino or another microcontroller. Read more.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
