Oscilloscope using Arduino interface LabVIEW

Oscilloscopes are used to observe the change of an electrical signal over time, such that voltage and time describe a shape which is continuously graphed against a calibrated scale. Due to the size, the cost and complex structure of oscilloscope there is need to alternative solution. This paper is focused on the new technology to use to observe the change of an electrical signal using Arduino interface LabVIEW that provides accurate measurements with small size device (Arduino) that can fit in the pocket which is also cheap device. The paper gives the brief introduction about the LabVIEW and Arduino, also the basic block diagram of the oscilloscope program along with its simulation results. The project has been test it with multiple signal voltages (+15 to -15) V Ac and DC and multiple frequencies (30Hz to 1 kHz) and it can measure more voltage Depends on signal condition circuit (the circuit that changes the voltage from .Any input voltage to Arduino input voltage (0 to 5) V) .The results that arduino Interface LabVIEW gave was the approximately same results as the actual results that Oscilloscope gave.
