Abstract: The Wireless Oscilloscope android application helps one to observe the waveform of the closed circuit. This application is supported by all Smartphone’s and tablet computers (Receiver’s) that work on Android operating system. Hence it is easy portable and easy installation. At the end of the closed circuit, Wireless Fidelity (Wi-Fi) Module is used to transmit the waveform signal over radio frequency and then is received by receiver using Wi-Fi. At last Graphical Waveform is reproduced in receivers
