Today, you will get to know the board with which you will implement the projects o
f
the next 24 days. To
prepare
f
or the next days, you will install the driver
f
or the USB connection, install the
A
rduino IDE and
fi
nally create your
fi
rst program
f
or the board
.
Chipset on the IoT-board
The IoT-board comes with two chipsets. For program execution, the board has an ATmega328P. This
micro controller communicates with an HC-05 via a serial interface. The HC-05 is responsible for the
wireless connection (Bluetooth). The module supports Bluetooth V2.0+EDR. You will need a Smart
-
p
hone with Android for A
pp
communication.
Confi guring the IoT-board
In order to take the IoT-board into operation, you need a computer with Linux, MacOSX or Windows
a
nd a Micro-USB-cable. This connection cable serves power supply and connection o
f
the IoT-board to
the PC in order to program it. You do not need to buy such a cable. You probably have one already –
a
lmost all modern Smartphones use this plug type
.
Select the
p
ro
p
er USB-
p
ort at the PC
Connect the cable to a USB 2.0 connection of your PC if you can. USB-3.0 connections may have con-
nection problems. You can often recognise a USB-3.0-connection by the blue socket.

the Arduino IDE, you can write the programs in the programming language C and trans

to the IoT-board. A

Switchin

off the IoT-board
The IoT-board has no off-switch. You
j
ust need to disconnect the USB-cable from the computer PC or
the mains unit, and the IoT-board will switch off. The last saved pro
g
ram will start automaticall
y
when
the board is switched on a
g
ain. The same happens if
y
ou push the reset button
