In the next slide, we will
give you a brief
introduction about them.

4. Arduino/Genuino Uno is a microcontroller board based on the ATmega328P
(datasheet). It has 14 digital input/output pins (of which 6 can be used as
PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection,
a power jack, an ICSP header and a reset button.

5. The Arduino Ethernet Shield 2 allows an Arduino Board to connect to the
Internet. It is based on the Wiznet W5500 Ethernet chip. The Wiznet W5500
provides a network (IP) stack capable of both TCP and UDP.

6. HC-05 module is an easy to use Bluetooth SPP (Serial Port Protocol)
module, designed for transparent wireless serial connection setup.

7. The LM35 series are precision integrated-circuit temperature devices with
an output voltage linearly-proportional to the Centigrade temperature.

Here we are implementing a Master-Slave Communication between two Arduino
Uno Board with HC-05(Bluetooth) and Sending orreceiving data to and from an
MQTT Client.
Here we are using Ethernet Shield to Communicate with MQTT Broker Adafruit and
interface out Board with it. Here we are also using two additional libraries of
Adafruit (Link is given below).
