Я в этом деле новичок. Пытаюсь подключить два датчика (GY-68 и Grove_High_Temperature). Ниже указаны скетчи:
#include <Wire.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_BMP085_U.h>
/* This driver uses the Adafruit unified sensor library (Adafruit_Sensor),
which provides a common 'type' for sensor data and some helper functions.
To use this driver you will also need to download the Adafruit_Sensor
library and include it in your libraries folder.
You should also assign a unique ID to this sensor for use with
the Adafruit Sensor API so that you can identify this particular
sensor in any data logs, etc. To assign a unique ID, simply
provide an appropriate value in the constructor below (12345
is used by default in this example).
Connections
===========
Connect SCL to analog 5
Connect SDA to analog 4
Connect VDD to 3.3V DC
Connect GROUND to common ground
History
=======
2013/JUN/17 - Updated altitude calculations (KTOWN)
2013/FEB/13 - First version (KTOWN)

Adafruit_BMP085_Unified bmp = Adafruit_BMP085_Unified(10085);

}
И второй скетч:
// demo of Grove - High Temperature Sensor
// Thmc -> A5
// RoomTemp -> A4
#include "High_Temp.h"
HighTemp ht(A4, A5);
void setup()
{
Serial.begin(115200);
Serial.println("grove - hight temperature sensor test demo");
ht.begin();
}
void loop()
{
Serial.println(ht.getThmc());
delay(100);
}
И, кстати, правильно ли написаны программки?
