FantomXR Posted December 23, 2014 Report Share Posted December 23, 2014 Hey folks, this is not the first time I run into this problem and I don't have a solution for that. So... I'm asking here. Here is the situation: I have an AINSER64. I want to plug three footswitches into the AINSER. I tried it like this: 5V o----/ ----o---|####|----o Ground | | | | +---- to A0 | | | 5V o----/ ----o---|####|----o Ground | | | | +---- to A1 | | | 5V o----/ ----o---|####|----o Ground | +---- to A2 Well, of course I run into the problem that A1 and A2 are triggered when just A0 is pressed. It's also the case when I put jacks in every socket. So my question is, how to isolate those sockets? Any tipps? Thanks, Chris Quote Link to comment Share on other sites More sharing options...
TK. Posted December 23, 2014 Report Share Posted December 23, 2014 With suitable resistor values the switches shouldn't influence each other. Which values are you using? Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
FantomXR Posted December 24, 2014 Author Report Share Posted December 24, 2014 These are 1k resistors. Quote Link to comment Share on other sites More sharing options...
ilmenator Posted December 24, 2014 Report Share Posted December 24, 2014 That's a bit on the low side - try something in the 10k range or higher. Quote Link to comment Share on other sites More sharing options...
FantomXR Posted December 24, 2014 Author Report Share Posted December 24, 2014 Okay, 10k works perfect! Thanks! Merry Christmas! Quote Link to comment Share on other sites More sharing options...
kpete Posted December 24, 2014 Report Share Posted December 24, 2014 Going from 1k to 10k ohms doesn't make sense to me. I would have suggested going to 100 ohm if your problem was coupling between wires. I wonder if your problem was a missing ground wire going to your resistors.
