The micro:bit has an accelerometer and magnetometer (compass) powered by ST’s LSM303AGR chip (https://www.st.com/en/mems-and-sensors/lsm303agr.html). According to the chip’s technical specs, in terms of acceleration, you can use the micro:bit to measure acceleration up to ±16g (1g being acceleration due to gravity, i.e. 9.8 m/s2—16g is 16x acceleration due to gravity). The micro:bit uses this chip to detect gestures but it can also be used just to read acceleration in 3 axes.
In this first part, I will show a method of setting the sampling rate and plotting the accelerometer data from the micro:bit.
It’s great that the Mu Editor will allow display of the data and plot it too.

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.
