Manual and Dial Phone Gate/Trigger

[SYNTHGUY57]

so far looks great and the screw stop idea is great too.

So you could use a TLO74 and get al 3 circuits used in one chip , the 2 outputs buffered and the pot/switch option also buffered . Nice and tidy . Just for notes the “buffer” is the factor putting pins1 to 2 and pins 6 to 7, right on a TLO72. Basic buffer no added resistors .

You can use your next phone dial to program a sequencer

Rotary Dial Arduino Input

I’ve used one to generate MIDI messages with an Arduino if that counts (notes and program changes)?

I didn’t want to replace or rewire anything inside though, so I’ve just used the signals as they come from the phone plug itself. This means I can unplug it from the Arduino and plug it back into a phone line and it still works (at least until they turn off pulse dialing in a few years time).
