    Garage door opener

    I would like to tap my garage door opener into my fusion brain. question i have with that is what kind of relay do i need? or mabye what i need in general. what i mean is, with a general on/off switch the relay sends a constant voltage signal to keep something on. but with the garage door opener it just needs it for a second. how would i go about doing that. thanks

    sorry for the horrible explanation. i dont know to many technical terms. thanks again

    Just use a regular relay, and tell the fusion brain to pulse the output for a certain numbr of milliseconds

    Exactly.

    This is what I will be doing myself soon. I hope you have seen the remote control part of the program so you can open it from anywhere in the world.

    Actually I just orderd the fusion brain and am inpationtly waiting for its arrival. I read alot about it but have not ran into anything about the remote control part. thats excelent!!!

    Hey I wanted to come back to this now since I got my FB working in my car and am loving it. How would I go about "pulsing the output for a certain numbr of milliseconds " for the fusion brain? and also it will still work with the road runner and RRfusion correct? thanks!

    To pulse you need to make some logic. First a button that changes a variable to true or to 1 or something other than false or 0 (or something you determine to mean off) as well as turn on the output.

    The logic then will monitor that variable that was changed to lets say 1. If that variable is 1, then another variable will be incremented. If that variable is 0, then the counting variable is 0.

    Another piece of logic that will now monitor this count variable. If the variable is over X where X is a number like 10, then turn the output off.

    So that 100 number is how long the digital ouput is on for. If the output timer is set to fire every 100ms (0.1s), then it takes 10 counts before the digital output turns off, and therefore (100ms per logic iteration) x (10 logic iterations) = 0.1 * 10 = 1 second pulse.

    Adjust the numbers for different values. If you change the timer to fire every 50ms still counting to 10, then it would only pulse for 0.5 seconds. Or Change the count to 42 and with the 100ms timer would be 42 * 0.1s = 4.2 seconds.
