Salam..hi..I have changed the project's software from Visual Basic to LabVIEW. Since DAQ card is used in this project which acts as the interface
between a computer and bio-potential signals from both wrist. Hence, LabVIEW
software are applied to complete the interfacing part. DAQ card is connected to
a computer through a slot or port.

LabVIEW programs are called virtual instruments or VIs, because
their appearance and operation often imitate physical instruments, such as
oscilloscopes and multimeters. LabVIEW contains a comprehensive set of tools
for acquiring, analyzing, displaying, and storing data, as well as troubleshoot
code. Hence this project block diagram are also been changed.

The Analogue to Digital Converter functions in
DAQ card is to convert a continuous quantity to a discrete time digital
representation so that the output could be read by the computer. An ADC may
also provide an isolated measurement. This will ensure the data from the ECG
could be displayed easily in the computer.

Hence, this project will have a better output waveform which appear on PC screen because in LabVIEW software it self have the filtering function to minimize noise.
