【简 介】:Change of the magnetism with rotation of a ball is detected and is operated.
・The output of the Hall element in the rotation direction (direction to which the ball is pushed) of a ball changes.(Example: If a ball is rotated in the direction of the upper right in the above figure, the Hall elements output of both H1 and H3 will change.)
・Resistors (R1-R8) are for hysteresis function.
・Each Hole element is connected to protection resistor.(200-Ohm at Vcc=3V)
・If you need the power down function, you need to control the power by FET or so.
・Above circuit is reference. It is necessary to care about the noise and layout of the signal lines.
