Q: Which microcontroller is used in this project?
A: A 40 pin microcontroller from 8051 family is used in this project.
Q: Why bidirectional rotation of induction motor is required?
A: Bidirectional rotation of induction motor is required to use the fan both in normal mode as well as in exhaust mode. .
Q: How to connect the motor in this project?
A: Operation procedure is provided with the kit,for connecting the motor.
Q: What is the role of microcontroller?
A: The microcontroller is programmed so as to change the direction of induction motor, with respect to the input.
Q: What is the rating of motor to be used in this project?
A: Single phase, ¼HP motor is used in this project.
Q: From what distance can the loads be operated using TV remote?
A: IR TV remote can operate the loads from a distance of 15 feet approx.
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.
