Lab Steps

After you finish each step, make sure I check it. You will get credit as you finish the steps in the lab.

 ① Coding the Alphabet

With your group, choose an english word and translate it into binary.

Don't forget to write the word in your notebook!

 ② Bread Board Basics

Use the breadboard to light up an LED!

Then answer theses questions in your lab notebook:

1. In the bread board are the columns connected?

2. What about the rows?

3. Draw a picture of your breadboard in your lab           notebook.

 ③ Build the LED Circuit

Play around with the bread board for a bit, and see if you can get 5 LEDs to light up.

Hint: Check the circuit diagram on the right!

red is positive

black is negative

  ④ Sending Signals

Use the your LEDs to display the letters from the word you chose in ①

Take a picture of your circuit displaying each letter of the word you chose!

  ⑤ Hello World

It's a tradition in programming to have your first program display the phrase "hello world." Use your binary circuit to display the two words.

6. How are you going to show a space in binary?

  ⑥ Notebook

Be sure you answered all of the questions and drew the pictures as well.
