Support  Arrow Forward  RB-x40  Arrow Forward  Using an External Switch

‍Overview

‍There are times when you want your RB-x40 response pad to detect the onset of an external input, e.g. a switch, a foot pedal, or even a TTL signal that’s coming from another computer. The light sensor input can double up as an external input. You will need a cable with a 2.5mm connector, available from Amazon and many others:

‍Adjusting Filters

‍When a mechanical switch is pressed, its contacts will “bounce” a few times, causing several signals to be produced. The size and quality of the switch determines how long it takes for the bouncing to die down. You can “debounce” the switches using a hold-on filter. See XID Filters and Signal Flow.
