timer help

[winston199]

I am looking for help with a 555 timer controller

thanks

What kind of help do you need?  I don't know how many people on here are into electronics, but I can try...

(I usually use PICs myself as they're just easier to do more with...more complex to get running than a simple little 555 circuit, though.)

controller for a diy wave box following schematic don't know what I am missing

[Funkmotor]

Well, I think I know the circuit you're talking about - if it's the one that uses the DIN-5 plug to connect to the Tunze controller box.

However, even if that's right I don't know what you now have or how far you've gotten.  Are you missing parts, or tools, or knowhow, or what?

I am using a beadboard to connect the parts and got everything the schematic has on it plug the parts in but wont work maybe part is faulty

[Funkmotor]

Well, only advice I can offer is to break the circuit down.  Check for the right amount of power in the right places, then put pieces in slowly and keep checking continuity.  Follow the circuit end-to-end with the point of a pencil so you are clear what is connected to what.

Do you have access to any test test equipment, an oscilloscope for example? That is quite useful for debugging ...

no equipment for testing
