Abstract
A smartphone application has been developed from scratch to perform an actual lab experiment in basic electronics in real time. The experimental circuit is interfaced with the smartphone with the help of the Arduino microcontroller board. Serial communication is established between the smartphone application and the Arduino through a USB On-The-Go or OTG cable. The smartphone application can then be used to plot the resulting data on an e-graph-paper mimicking an actual graph paper. Intelligent methods of curve-fitting may be employed and experimental results obtained automatically, all in real time and without the need to touch the experimental set-up.
