how do you use a breadboard?
how do you use a solderless BREADBOARD i just got it and i need help on how to use this thing
Update:well my comes with a wire like um... a power cord yea and i JUST WANT TO NO HOW TO USE IT

Using a Breadboard
1. Before building a circuit, connect power to the red terminal. For a battery pack, connect the positive (+) from the battery pack to the red screw terminal. Since ground is a reference voltage, connect the negative (-) from the battery pack to the black screw.
2. Unscrew the terminals and connect the battery pack, as described above. Screw the wire down firmly so that it doesn't move, but not so firmly that the wire is cut.
3. If you are using a power supply, simply connect power to the red terminal on the breadboard with a banana plug to a banana plug cable. There will be a ground connection on the power supply that can be connected to the ground terminal.
4. Once power and ground have been connected to the board, connect a wire, also known as a jumper wire, from the red terminal to the power bus (the red highlighted row). The wire should be just long enough to span the distance between the terminal and the bus.
5. Take the wire and strip off ¼ inch of insulation from both ends. Connect the ground to the blue highlighted bus. Make sure the wire is just long enough to span the distance between the black terminal and the bus.
6. Strip off ¼ inch from both ends and connect the ground bus to the black terminal. The breadboard is now ready to have a circuit built upon it.
The surface of the board will have a channel which separates the surface into two areas.
Consider the holes as rows which are at right angles to the channel.
Most people use the board oriented so that the channel runs left-right, not up-down.
The holes along the rows are connected together underneath the board.
So what you have is, effectively, strips of wire at right angles to the channel, and each of those strips of wire have little sockets on them, one under each hole.
Another name for the wires is busses, or busbars.
You can plug in a transistor by inserting the emitter, base and collector leads into holes in adjacent rows. You now have one bus with lots of other connection points on it connected to the emitter, another to the base and a third to the collector.
To those busses you can connect resistors, capacitors etc, with their other ends plugged in to other busses as required.
It takes a little getting used to, but you'll soon get the hang of it.
The channel is spaced so that a TTL or CMOS chip may be plugged in with one row of its pins on one side of the channel and the other row of its pins on the other side. You will then have a bus for each pin running at right angles to the channel.
