Step 4 Hook Up Your Microcontroller

This step really depends on the type of Micro Controller you use, I will be using the Parallax Basic Stamp 2 micro controller. If you have a different type of Micro Controller such as the Make Controller, and you need some help, feel free to ask in a comment.

You will need to hook up the LED's and speakers in the exact same place as I show, or the program that I will include in the next step will not work. In the 14th 13th 12th and 11th rows, plug in 470 ohm resistors leading into the far set of rows under the Vss terminals, the resistors should lead into the same row as they came out of. Now take four different LED's and plug the negative (shorter end) ends of the LED's into the Vss terminals. Take the positive ends (longer ends) of the LED's and plug them into the same rows as you plugged the resistors into (rows 14, 13, 12, and 11) The two ends of the speaker should be plugged into row 9, and into one of the Vss terminals, using a longer wire if necessary. If you are going to use a computer speaker to amplify the sound, just hook up the wire coming out of terminal 9 to the input wire of your computer speaker. The pictures should make all of this a lot clearer if this was confusing for you.
