AM2302 (DTH22) on Adafruit Feather HUZZAH reporting via Wi-Fi (step 4)

Next we’ll connect the Feather to Wi-Fi and report the temperature and humidity data to a cloud MySQL database server through a web page. Using the MAC address for the Feather you found in step 2, register the Feather on Devicenet. Paste the is sketch and make necessary edits (indicated with //TODO): // https://github.com/openhomeautomation/esp8266-cloud/blob/master/cloud_data_logger/cloud_data_logger.ino // … Read moreAM2302 (DTH22) on Adafruit Feather HUZZAH reporting via Wi-Fi (step 4)

Get the MAC address of an Adafruit Feather Huzzah Arduino board (step 2)

Create a new sketch with the following code and upload it: #include “ESP8266WiFi.h” void setup(){ Serial.begin(115200); delay(500); Serial.println(); Serial.print(“MAC: “); Serial.println(WiFi.macAddress()); } void loop(){} Open the serial monitor (magnifying glass). Press the reset button on your Feather. You should then see the MAC address associate with the wireless Ethernet radio on your Feather appear in … Read moreGet the MAC address of an Adafruit Feather Huzzah Arduino board (step 2)
