PC based Oscilloscope using Freeduino Board and plot in Matlab

[ritika.lavina]

We have designed an Oscilloscope using PC and Arduino Board. The signal is first of all fed to the Arduino Board where the analog signal is converted to a digital signal by the ADC which is then serially outputted to the PC and is read by the MATLAB software via the COM ports. Here the signal is read in the form of digital data but then is converted to analog one by using the resolution of the ADC used by the Arduino Board. the MATLAB software was then used to plot the signals.
