1 Mbps!

8. HC-05 Bluetooth Module:
 The HC-05 small size Bluetooth TTL transceiver module are
designed for serial communication (SPP - serial port profile).
It allows your target device to both send or receive TTL data via
Bluetooth technology without connecting a serial cable to your
computer.
It has Coverage up to 30 ft / 10 m with Built in antenna.
It has Power input: +3.3VDC (bluetooth module).

9. PUSH-PULL four Channel Driver with Diodes
Designed to accept standard DTL or TTL logic levels and
drive inductive loads and switching power transistors
Suitable for use in switching applications at frequencies
up to 5KHz
It is assembled in a 16 lead plastic package which has 4
centre pins connected together and used for heat sinking.

11. What Is Android:
Is an operating
system based
on Linux
Kernel
It is designed
primarily for touch
screen mobile
like smart phones
and tablet computers
User interface of
android is based
on Direct
Manipulation
Internal hardware such
as accelerometers,
gyroscopes and proximit
y sensors are used by
some applications to
respond to additional
user actions
