PWM — A NEW OPPORTUNITY

PWM — A NEW OPPORTUNITYFor the computer control various devices and objects I propose to use the method of pulse width modulation (PWM) is equally successful when working with different PCs: Intel-80286 to Pentium latest modifications. Perhaps, the only condition — the presence of a free com port. The relationship with him is up to 200 m can even be done through conventional telephone wires, no protection against the electromagnetic effects of the environment. In the transition to the more sophisticated, shielded lines of the “range” computer control with PWM increases.
