I soldered a sw-18020p sensor on k1-gnd pins but it does not work,is the sensor too quick to be detected or io pins pull too much current(max ma on 18020p is 30ma iirc and closed ciruit delay is 2ms-1ms)
Another issue is what circuit can i use to turn off jq6500 when busy pin is 0v , transistor?( Bc328 or others)
I have another project that uses a pro mini and a jq6500, can i use arduino with transistors in that project to turn it off?
If the ciruit is too complicated i might as well buy those 120s sound boards but i dont know if my sw-18020p's are going to work on that board
