wire library between arduino uno and adafruit feather

Within TheThingsNetwork we use the LMIC-Library , slightly modified to run in the Arduino environment, allowing using the SX1272, SX1276 tranceivers and compatible modules (such as some HopeRF RFM9x modules).

readTemperature() // save the value of temperature to temp variable Hum = dht.readHumidity() //save the value of humidity to hum variable begin() //initiate the communication with sensor #define DHTTYPE DHT22 // define type of sensorĭHT dht(DHTPIN, DHTTYPE) //define properties of sensorĭht. #include 'DHT.h' #define DHTPIN 2 // define data pin on Adafruit, we used 2

Check if your Adafruit Feather can simply read the temperature and humidity from a sensor using Arduino IDE simple sketch:.

For communication with DHT22 we need Arduino library for DHT11DHT22, etc Temp & Humidity Sensors, import it to Arduino IDE.

Check the picture below to make sure you are actually using the right pins. You can use a simple wire bridge for that.

You need to additionally wire up the board’s IO1 pin with the board’s pin 6.

Use an addition 4.7k resistor between +3.3V and the data line.

For data, we can use any of available digital pins, see here

Connect the one wire temperature sensor DHT22 to Adafruit.

Temperature Sensor using Adafruit Feather 32u4 and DHT22

Check the appropriate COM port which is used for communication with Adafruit.

Connect the Adafruit Feather using directly micro USB cable (no FTDI adapter is needed here).

You should see in menu Tools -> Board the Adafruit Feather 32u4.

Install the Adafruit boards via Tools -> Boards Manager.

Copy and paste the link below into the Additional Boards Manager URLs option in the Arduino IDE preferences. You will need to install the Adafruit Package in your Arduino IDE.

Feather 32u4 LoRa Radio uses the extra space left over to add an RFM9x LoRa 868/915 MHz radio module. At the Feather 32u4‘s heart is at ATmega32u4 clocked at 8 MHz and at 3.3V logic.
