How to use a 555 timer to switch a switch? Answered
I was thinking about making an intervalometer circuit for time lapse use on cameras. I was thinking of using this link https://www.instructables.com/id/Time-Lapse-Intervalometer-for-SLRs-with-555-timer-/ .
I was thinking of adding a 22uf cap, as well as the normal 220uf cap, and then adding a 2200 uf cap, for a highly flexible range of time (ranging from a few seconds to about an hour), choosable by switch. I am starting to run into trouble at the camera connection itself. While i am fine with a cable, i would rather go with a wired remote, and using it to do the equivalent of pushing the remote buttons (instead of going through the cable itself). So i need a way to connect the two switch points electronically, rather than mechanically. Also is there a way to have it focus first, then take the photo? This circuit would also be good for cameras that do not have remote connectors, just go in to the camera and solder the switch points up, then hook them to this circuit. Would also work with a wireless remote. Hook it to the remotes switch and go from there. Just need a little help finding out what to do to get it to work the way i want to :) Thanks
