I was having trouble with the inputs of the up/down pins of the 74192 I am either trying to use a switch to toggle between the up and down. Or I am trying to use two hall effect magnetic sensors that are being inverted with a 7404 to increment or decrement the count on a 7 segment display. If any knows a solution I would appreciate it.

I am using 1k resistors as a pull ups and the count works fine for the down count but the up count is incrementing by two each time the sensor is triggered. Thanks for the response.

Does the down count work properly when you use a switch instead of a sensor?

Could you post a schematic? You may have noise coming in somewhere or something else going on.
