Batteryless Persistence- of-Vision Toy

Design a batteryless POV toy that is programmed with text and graphics patterns in a microcontroller. The toy uses seven LEDs arranged in a column, which is waved through the air. These LEDs are controlled by the microcontroller, which generates a pattern of light on the LEDs that an external observer sees as a message or graphics due to the persistence of vision. The operating power for the toy is derived from the Faraday generator.
