wpt

WPT (Wireless Power Transfer) is a technology that allows electrical energy to be transmitted wirelessly from a power source to a device over a distance without physical connectors or wires. It works through principles of electromagnetic induction, magnetic resonance, or electromagnetic radiation. WPT is commonly used in applications like charging smartphones, electric vehicles (EVs), medical devices, and powering IoT sensors.

There are different types of Wireless Power Transfer systems:

1. Inductive Coupling: This is the most widely used form of WPT, where energy is transferred via magnetic fields between two coils—one in the transmitter (charging station) and one in the receiver (device). The distance is typically short, within a few centimeters.

2. Resonant Inductive Coupling: This allows for longer distances and higher efficiency than inductive coupling by using resonant frequencies between the coils. This is used in medium-distance applications like EV charging.

3. Capacitive Coupling: Energy transfer is achieved through electric fields between two plates, but this method is less common and used for specific applications.

4. Radiative WPT (Microwave or Laser-based): This transfers power over longer distances by converting energy into microwaves or lasers and then directing them towards a receiver. These are still in the experimental stage for applications like space-based solar power.

If you're planning to work on a WPT project with Arduino or any other microcontroller, you would typically:
