Here is how to assemble a flashing
led on a breadboard. This is a good thing for getting used to
breadboards and assembling circuits and all that stuff. You will need the following parts:

Find some space for your
breadboard. Put it horizontally with the red stripe (if you have one)
at the top. (unlike this picture)![]() This is the circuit were gonna build ![]() |

Insert the LED with the negitive side on the resistor. ![]() You can usually tell the polarity by what I call 'Anvil' (negitive side, 'cathode') and 'Post' (positive side, 'anode'), in this pic, you can see the anvil on the left and the post on the right. ![]() |
