Led Light

How do I wire something like a timer to an LED light?

I want to learn how to wire things to other things.

I want to be able to wire a timer, and when it goes off, it turns on the LED light. How do I do that? I've Googled, searched for questions here, but no results. I'm looking for a best answer

Here's a link that covers using a 555 timer in a one-shot mode:

Here's a link covering making it flash:

From your question, I think a more basic approach would be useful.

One way to start is to get very simple kits (I found several on sale for $2 - $3). Look locally, and on the internet. Fancy ones can be over $50 each!

A more educational way is to work your way through a beginner's lab kit, here's an example:

More advanced kits require soldering. Here's some kit building instructions:

If you want to do much experimenting, you really need a power supply and prototype board. This allows you to build circuits without soldering. Of course, the components must have leads. The most deluxe way is to go $70 for a station with supplies built in. Or, economy and medium options below:

Economy supply: 5V@1.5A, 12V@1.5A, $5+$2cord

Economy protoboard model: $10 with 3 binding posts and wires:

Nice supply, 5V@6A, ±12V@2.1/0.3A, $13 +$2 cord. ±15V supply is better if you can find one cheap. For this one, just cut off DIN plug, strip wires, and put in binding posts: http://www.mpja.com/prodinfo.asp?number=17507+PS

Really nice protoboardwith with 4 binding posts, distribution strips across the tops, and jumpers, but its $19.

You will eventually need tools also. I recommend a digital multimeter (DMM), hemostats, end nippers, cutters, soldering iron with solder (adjustable station prefered, one of the suppliers has one for $15).

Here's links to several sites to buy parts cheaply:

These seem to be about the best:

Goldmine has components like the 555 timer is you are interested. Also, both have switches, pot's (variable resistors), and other components. Use a pot for the timer circuit, it changes the LED timing when you adjust it.

Good luck!
