ND gate 1,2 composition. When touching conductive sheet M while, Ai Kai vibration that is to CC4017 ~ - into the counting/pulse divider Az issued counting pulse, the output of Yl A2 of ~ Y9 turn out high through different resistor values R ~ ~ Ria buck to the optocoupler B, and then control the TRIAC V conduction angle, to achieve eight gear speed. Resistors R6 level 62kC1, R7 ~ R1a required to determine the actual debugging, so that two adjacent block electrical pressure (voltage across the motor) the order of 25 ~ 30V.
