The paper uses Arduino Microcontroller to design a Modified Sine Wave Inverter. It employs Fourier transform to
mathematically analyse its harmonic contents. It was shown that by eliminating third harmonics present, distortions
can be reduced. The paper employs step by step methods to design various stages having, Transistor and MOSFET
switches. Arduino codes were written using digitaWrite() and delayMicroseconds() functions in its Integrated
Development Environment IDE to generate drive waveforms. It highlights how Arduino sketch could be compiled and
hex files generated for simulation in Proteus ISIS. Power Transformer Simulation technique was explained. It is believed
that proliferation of Inverter technology will enhance economic prosperity especially in the third world countries where
dearth of electrical energy is being experienced. The design includes Liquid Crystal Display for the display of generated
voltage and frequency. It is recommended that future improvement could be improvement in Liquid Crystal Display
functions with robust programming that would foster ease of interactions between the device and the users.
