Hello,
i want to drive a motor with an Arduino nano and a Adxl345, it use to work but now i got a serial error
on the JRK21V3. It should keep a basket horzontal for a handycapt person who needs oxygen.
I build this in 2016 and it worked. Now i have to build another one but it won`t function.
The code is below, can someone help me ?
#include <Wire.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_ADXL345_U.h>
#include <SoftwareSerial.h>
SoftwareSerial mySerial(10, 11);
