You can construct a wide variety of projects
with E-blocks. On this page you can see a few
examples:
Figure 4 shows a simple internet based
temperature logger. The PICmicro microcon-
troller 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.
Figure 5 shows an electronic bug using mobile
phone technology. 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 go-
ing on in the room. A keypad and LCD allow

various set ups with dial out at pre-deter-
mined times.
Fig 6 - ARM based Bluetooth system
Figure 6 shows a project which uses an ARM
microcontroller to communicate to a mobile
phone using Bluetooth. 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.
Fig 7 - ECG system
In figure 7 you can see an Electro
CardioGram(ECG) data logging 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.
