Examples of E-blocks systems
You can construct a wide variety of projects
with E-blocks. On this page you can see a few
examples:
Internet based temperature logger
The PICmicro microcontroller gathers data
from a temperature probe via the sensor
interface and then publishes a simple web
page with a 10 bit temperature reading. A
further program - written in Java - gathers
temperature data from the web page and
produces a graph of temperature against
time.
Mobile technology snooper
A small patch board contains a microphone
and amplifier that feeds into a Sony
GSM module with SIM card. An AVR
microcontroller is used to detect an
incoming call and then channel local sound
to the incoming caller who can hear what
is going on in the room. A keypad and
LCD allow various set ups with dial out at
predetermined times.
ARM based Bluetooth system
The Bluetooth board interfaces to the
ARM serial port to allow users to set up the
communication system and transfer data
between Bluetooth hosts. The Bluetooth
audio CODEC board allows two way transfer
of audio between Bluetooth systems.
ECG system
ECG data is gathered using a sensors board
and an ARM microcontroller board which
connects to a PC using an USB interface
board. PC software, written in Visual Basic,
uses the virtual COM port driver provided
to interface with the system and gather ECG
data. A Keypad and LCD display provide
control of the system.
