I checked the hookup guide and am seeing that the “LED enable” joint should be desoldered to control the LED separately, so I did that for all 4 sensors but still seeing glitchy unstable behavior. Did I mess up these 4 from all this tinkering? I have a bunch of spare touch sensors, but at $7 a pop, I’m hoping not to need all new ones.
I feel like pull-down resistors are the way to go. I will explore the user guide and datasheets more deeply but some of it is over my head…
