Q:  Why is only Android smart phone used?
A:  An Android smart phone provides wide number of free applications. Hence it is used.
Q:  Which microcontroller is used in this project?
A:  A 40 pin microcontroller from 8051 family is used in this project.
Q:  What is remote AC power control?
A:  Controlling the AC power supplied to the load using a GUI based Android application is remote AC power control.
Q:  Can I place motor instead of lamp?
A:  Yes up to ¼HP 230V AC motor can be used.
Q:  Which Android App is used in this project?
A:  BlueControl App is used which is freely available in Google Play store.
Q:  What is the formula for calculating smoothing capacitor value?
A:  There is some approximated formula .Peak to peak ripple voltage = Load current in amps / (2*line frequency in hertz *capacitance in farads). But as rule of thumb for 1 A current 1000uF is best. Thus it is load dependent.
Q:  What to do when the lamp fails and what is the maximum lamp rating that can be used?
A:  If the lamp fails one can use any lamp or bulb which is used in homes up to 100W. We suggest you to go for low watt bulbs.
