Did it work? If not, get help from your teacher.
Part 3) The Code. Writing Text. Hello World!
|
Type up this code to the right then check it (verify), upload it to board, see if it works. If not, check if you have the screen wired correctly like the picture above.
Did it work? If you got it to work, then play around with the text size, color, cursor positions, and actual text you want to type. You can add more lines by putting more display.println(" ") rows. Email Mr. Dorsey a picture if you make something really cool. |
