In this project, you will continue to explore the two major parts of every program you'll write here: setup and loop. Start thinking about your code this way: What should repeat again and again and what only needs to happen once?

/* * In this project, you'll build on the text message you showed in lesson * one and learn a new method from the MakerScreenXVI library to control * items on the screen. */ #include "MakerScreenXVI.h" MakerScreenXVI lcd; void setup() { lcd.begin(); lcd.backlightOn(); } void loop() { /* * If you tried putting the lcd.print into loop without anything * else, as suggested in the previous project, you saw how the * text was pushed along the screen. That's because the screen * starts writing wherever it left off after the last print. */ // lcd.clear is a method that resets the screen, clearing off // old text and putting the cursor in the upper-left of the screen lcd.clear(); lcd.print("Hello world!"); } /* * In this project, you changed something on the screen over time by * printing the message in the loop. You got a taste of how fast the * Maker Board is: when you print and clear only, the screen flickers * really badly. Next, you'll use a new function to slow it down. */ //(c) 2017 Let's Start Coding.

Try copying and pasting some of the code statements from void loop into void setup and vice versa. Remember that you should not copy or paste the braces { }. If you receive an error when you try to upload the code, just undo the change or press 'Restore' in the upper-right of the code window.
