Could anybody let me know the principle how up down counting is done using 2 micro switches or proximity switches. I can figure out the electronics to start counting up or down.
If i have 2 sensors, (proximity or on/off switches) , what is the principle and wiring of the switches , used to make it count the number of turns of the wheel, increasing clockwise and decreasing anti cw . The wheel is hand turned and will have a cam or plate to activate the switch or proximity switch serially or one after the other.
thanks

You need a quadrature detector such as this.
