20210506· A logical approach, is to "condition" the signal at the Arduino end with a 10k resistor after the pullup, and a 5µF capacitor. Rather than altering the pullup, it would make more sense at the sensor, to use a 10k pullup and a 74HC14 with one inverter feeding the other five in parallel, as a buffer. youngengineer October 24, 2014, 6:20am 4
