This paper presents the “Automatic control of home appliances include Room Light and Fan Controller Using Microcontroller AT89C51” is a reliable circuit that takes over the task of controlling the room fan and room lights as well as counting number of persons / visitors in the room very accurately .When somebody enters into the room then the counter is incremented by one and the light in the ro...

This paper deals with the implementation of automatic power factor correction system using solid state switched capacitors and Arduino UNO controller. The main objectives are to reduce the line loss, to reduce reactive power flows on the line and to avoid switching surge overvoltage due to switching on/off the capacitors. This paper describes the design and simulation of power factor correction...
