Hi everyone,
A bit of background first, I know only the basics of electronics (ie: I know what components do and how to read schematics), but have no idea how to design circuits, hence why I'm coming here for help.
Now to the (slightly odd) circuit.
- In essence I simply need to trigger a DC motor to turn for a fixed amount of time.
- The switch that triggers the motor will be a push switch that may be only pushed briefly (not held down 100% of the time). The switch, once pushed, needs to be 'deactivated' so that pushing it again wont trigger the motor to turn again. I assume it then needs some sort of 'reset' button to activate the switch again?
- Also, I need another switch that will reverse the direction of the motor so that it turns backwards for the same amount of time it was set to turn forwards in the first place. (no need for the whole deactivation/trip protection in this one)
- If the reset switch and reverse switch could somehow be one in the same thing it would be awesome, but really doesn't matter that much if I use two separate switches (so three in total)
I was thinking a 555 timer to control the whole motor timing thing, and a triac to control the whole switch re-trip protection/one push triggering thing. How (or if) it could all fit together I have no idea. I would like to keep it as simple as possible, and I don't have the tools (or budget) to program anything on a microcontroller. I realize that I'm asking a lot, and of course I would love some free advice
, but if someone is willing to design the whole circuit (schematic and all), then i would also be willing to pay (via paypal).
So, any ideas?
oh, and feel free to pm me if you'd be willing to design it for me/give me a quote.
Thanks!
Sean
