Mini project is on Intruder alarm it is implemented using IR sensors. And major project is on Implemention of an Efficient Updown Counter using Adiabatic Logic. Adiabatic logic is a new logic being used in the place of CMOS logic. The signal energies stored in the circuit capacitances are recycled instead, of being dissipated as heat. The Adiabatic logic is also known as energy recovery logic.
