Ammolytics Project: Inexpensive Firearm Accelerometer
- Adafruit LIS3DH Triple-Axis Accelerometer
- Adafruit Feather M0 Bluefruit LE
- Adalogger FeatherWing - RTC + SD
- 3.7V 500maH LiPo Battery
- 3D-printed mount
There are excellent guides available from both Adafruit and Sparkfun which explain how to wire the sensor correctly.
And another for how to setup the RTC date/time and write to the SD card.
After assembling the hardware, you'll need to install the software in this repo onto the Feather board. For use at the range, I recommend disabling the
DEBUG flag by commenting out the following line:
// Enable debug logger. // Note: Comment out before running in real-world. #define DEBUG
