Crazy Lee Posted December 10, 2016 Share Posted December 10, 2016 Wow. Forgot this board existed. Anyway. @Lopaw, anyone else who knows electronics. I'm trying to set up something electronic for the holiday. The details are thus: The device I have has a 5v or so power, a ground, and most importantly, a signal or "mode" pin. The pin allows you to switch modes in the chip-controlled device. Now, here's how the device works. You apply power to activate it, of course. It does a quick start up cycle and then stays on in the first "mode". Every time you ground the mode/signal wire, it switches modes. I considered using a 555 circuit to ground it on a regular cycle (and maybe a pot or rheostat to adjust the cycle frequency). Here's the thing though. The cycle for the device every time the mode wire is grounded is "mode 1-off-mode 2-off-mode 3-off...." in other words it turns off in between each mode. If you ground the pin it either goes off or to the next mode. Also, it doesn't matter how long you ground the pin, it only switches each time it's grounded. So you could ground it for 10 seconds and then stop and it would only switch once. Honestly it seems easiest to control with a microcontroller board. But, I wondered if some kind of IC setup could run it as well. Anyway, something I'm working on. Quote Link to comment Share on other sites More sharing options...
