What's a bread thing? A bread-board is a board made of bread, so you can easily poke and plug stuff into it, no, it’s a plastic board you can poke and plug things into. Most of the time Bread-boards are used for prototyping before fabricating Printed circuit boards.
What's an Arjuno? An Arduino uno, simply, is a basic computer brain. It’s used to basic, rudimentary programming for beginners learning how to program. The Arduino uno connects to the computer via a old-style usb plug where the user can program it as the user sees fit. So far the user, we, have been able to use the pre-programmed script for flashing and blinking an LED light. Using this script/program we can lengthen or shorten the amount of time for the LED to be on or off.
How can I resist? We use resistors because if we didn’t most of our electronics would EXPLODE. Think of a resistor like taking a big water hose then stepping it down to a smaller hose. Think of Ohm’s law much the same. Voltage is the supply of water, current is the tube, and resistance is the size, diameter, of the tube. Imagine if your bath tub’s water head was connected to a river and you got the flowing force of that river as soon as you turned the thing on, it wouldn’t be very nice, now imagine if you had a big supply of water, the river, connecting to a tank of water, and on another side of that tank there was a little spout that spat out nice low pressure, calm water. On top of all this those little colorful bands on the resistor are not decorative, they serve a purpose, that being to tell what resistance (ohm-ige) the resistor is.
What's Lead? LEDs are polarized, what this means is that you must plug them in a certain way for them to work in this case being positive to positive and negative to negative. The LED has two legs, one longer than the other, the longer one being for the positive side, I think.
