The Control of the Modified Meter of Flight Equipments

This article is to do a research for flight simulation modified meter, to design a basic control circuit of stepping-motor modified meter, to control the signal supplied by PIC MCU, and get to the result of clockwise and anti-clockwise rotation, speed regulation, reversion to zero position of index and other controls. The control request can be achieved as a real modified meter after the improvement under the foundation of the basic control circuit.
