can i use a hall effect and magnet to make 0 to 100% you just let me know how pwm works! it is full votage and just pulsed to go slower. like tappin...

there is a filter unit that will take out iron calsium and other material it back flushes to clean it self. if you plumbed the unit correct you could ...

maybe this is easier to explain, ((((( i want to use a rotary pot of 90 degrees that has a output of 0 to 5 volts CW rotation, ( it is a hall effect...

IF I USE A POT I DO NOT NEED THE ARDUINO CAN USE A MOSFET AND RESISTORS AND ROTARY RESISTOR. I NEED 50 AMPS @ 12 VOLTS. THE ARDUINO I COULD DO A LOT...

THINK OF A RADIO CONTROL CAR AND THE TRIGGER TO MAKE IT GO FORWARD IT ONLY MOVES LIKE A TRIGGER ON A GUN. YOU PULL IT BACK THE CAR GOES FORWARD LET GO...

instead of a resistor can a use a rotary encoder to ramp the voltage of 12 volts dc from 0 to 12 volts but only use 45 to 60 degrees of rotation? i wa...

I NEED TO SAY ONE MORE THING! I LIKE THE NO CONTACT ENCODERS BECAUSE A POTENTIOMETER HAS CONTACT AND HARDER TO MOVE.

@fpeter3 A CAPACITOR WOULD KEEP IT GOING UNTIL YOU MOVED AGAIN! DEPENDS ON THE SIZE OF CAP YOU CAN PUT IN THE MACHINE AS TO HOW LONG IT WILL LAST BEFO...

THIS IS WHAT I WANT TO DO! I WANT TO USE A ARDUINO PWM, CONTROLLED BY A ( 0 TO 5 VOLT DC ROTARY HALL EFFECT POT ). OR I CAN GET A 5 TO 0 DC VOLT HAL...
