In this tutorial, they explain very well how to set it up.įollow this step-by-step video. STEP 4: Connect ESP8266 to Firebase to Send & Receive Data You can follow this tutorial to get it working. STEP 3: Connect the other Arduino to the DHT11 Sensor

Understand that you are not connecting the Arduino to the internet, you are connecting the ESP8266 to the internet You can later send data between the two boards via the Serial terminal.įor this part, you can use either I2C communication as we did or normal communication.

You use the Arduino UNO to communicate with the ESP8266. Note that they work as two different boards and have different codes.

STEP 1: Understand how Arduino UNO and ESP8266 work together. Send this data to Firebase using an esp8266 module and then download the data in another Arduino UNO using an esp8266, to finally display it onto an LCD.

7 bits identify the device, and the eighth bit determines if it's being written to or read from. There are both 7- and 8-bit versions of I2C addresses. Because of this, send() and receive() have been replaced with read() and write(). The Arduino Due has two I2C / TWI interfaces SDA1 and SCL1 are near to the AREF pin and the additional one is on pins 20 and 21.Īs a reference the table below shows where TWI pins are located on various Arduino boards.Īs of Arduino 1.0, the library inherits from the Stream functions, making it consistent with other read/write libraries. On the Arduino boards with the R3 layout (1.0 pinout), the SDA (data line) and SCL (clock line) are on the pin headers close to the AREF pin. This library allows you to communicate with I2C / TWI devices. Reference Language | Libraries | Comparison | Changes
