Lets start a new project, shall we?

Hi everyone,

it is Wednesday and somehow this day just wont end. Im bored so i took my time to thought about this post and I think I've got an idea that could be interessting for my loyal followers :D

Today we are going to do another project. The last one was somehow not thaaaaat amazing. But when we're done and we do everything right we will have an...

automatic drawer o.O

What can you expect from that? Well, lets all imagine we have a little button. As long as we press the button, our drawer will move automatically into one direction until it cant go any further. Then it can only go into the other direction until it is closed again.
 Sounds simple, right? Well, if it is so simple, try your best and tell me how it worked without my help ;P

But to understand how all of this works, we have to understand how a realy works.

A relay is rather simple. You put voltage onto one side and all switches of the relay swtich. Did you understand that? No?







 At first, the switch 1 is non-conductive (S1) and switch 2 is conductive (S2). Now, when the current flows through the coil, the switches change so that S1 is now conductive and S2 is non-conductive. You also see that the lines between the switches 1, 2 and the coil are not connected.
 This is really usefull if you want to switch different current circuits with one signal.








Now we know about relays. This will come in very handy for your project.

Bye :D

  5. Heh sounds like it's going to be a fun project :) I don't really use my drawers though. Sometimes I'm amazed I have one.

  7. We don't use relays anymore though?

  9. Relays and circuits are complicated, but I'm going to be following this one :D
