## How to read and write in ASCII

The first thing you need to know is that each key is eight numbers, either 1 or 0. In ASCII, think of the number 1 as on, and 0 as off.

Each number equals a certain value. ___ ___ ___ ___ ___ ___ ___ ___.

128 64 32 16 8 4 2 1

The first three numbers are the easiest. 011 is lowercase and 010 is uppercase.

The next five numbers get a little trickier. Remember when i said 1 is on and 0 is off? This is where that comes into play. The number each letter in the alphabet has a number. (i.e. a=1 or d=4) The number the alphabet is is the number the five last number equals up to. Like the number for J's last five numbers are 01010, because J tenth letter in the alphabet and 01010 is ten. (0 + 8 + 0 + 2 + 0 = 10) Then you put the first three numbers as 010 or 011 to make the letter capital or lowercase and TA-DA! You have written your first letter in ASCII! Ready to go on?
