The LED cube has 64 LEDs (4x4x4). Each LED is dedicate an IO port in a microcontroller. LED cube rely on optical phenomenon called Persistence of Vision. If you flash a LED really fast it will remain in your retina for some time even after LED is switched off. By flashing each layer of cube very fast after one another it gives the feeling of 3d. With this setup we will need only 16(anode) + 4(layers) IO ports to control each led. LED has two legs one positive and one negative.

The basic aim of this project is to transmit electric power wirelessly.Wireless Power Transfer (WPT) or wireless energy transmission is the transmission of electrical power from a power source to a consuming device without using solid wires or conductors. Wireless transmission is useful to power electrical devices in cases where interconnecting wires are inconvenient, hazardous, or are not possible.
