I rather imagined an inverting Gate/Trigger pulse signal, so i think it’s an “inverted positive pulse (0V when switched pushed else 5V)” for the ~7V i take it in this topic > [@Need Help: Manual Trigger, 0-5v Out](https://lookmumnocomputer.discourse.group/t/need-help-manual-trigger-0-5v-out/360/9): > > What do you plan to connect it to? If it’s a high impedance (i.e. buffered) input, you can just use a simple voltage divider, like Bitnik suggested [above](https://lookmumnocomputer.discourse.group/t/need-help-manual-trigger-0-5v-out/360/2). If you have a +5 V supply, you can just use a pot as a voltage divider directly, with e.g. a 1k on the way out to limit the current in case you plug it in in the wrong place: If you only have +12 V, add a resistor before the pot to shave off 7 volts: EDIT: you may still want to include the… if this circuit give me 5V and not 7V i think it’s still ok for Trigger/Gate signal . I think if i use an opamp for an invert out, and i take a TL072, i can maybe add a second output like this ![manual dial phone gate - Copie](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/2X/f/ff2ce3f604e9e306090c95b519d4063aa16a528f.jpeg) or not ? 😀 thx --- _[View the full topic](https://lookmumnocomputer.discourse.group/t/manual-and-dial-phone-gate-trigger/1961)._
