Arduino Impact sensor with BLE

Inspired by the Adafruit based impact sensor at BE conference 2019 at the SSIS this project was be recreated with an Arduino, an MPU 6050 for +/-16g and a C2421 BLE module.

Code:

2019-11-15

// MPU6050 connected with i2c to ESP32

#include <machine.h>

static RTC_NOINIT_ATTR int reg_b;

#define acceleration 9.81


void main () {
	uint32_t time = 1914
	measureAcceleration(time);
}

Alternative:

ESP32, MPU6050, LiIon Battery and OLED display for recent max acceleration. All soldered together to be packed into a rubber duck.

Rubber duck debugging

Not to be confused with Rubber duck debugging. Even though we try and perform this from time to time.
