Showing Data on the Maker Screen
Interacting with the real world is one of the most fun things about using Maker Board to code. Maker Screen can display readings from all sorts of sensors.
In this example, you'll see how to take a light reading from a light sensor. If you don't have a light sensor, you can plug a button into A5 and GND and press it to change the reading. Here's the code.
This is just one example of using data to show on the Maker Screen. The lcd.print() method can print a variable value, a direct reading (like analogRead(A5)), or a string of numbers or characters.
You should be able to display almost any reading you can take with Maker Board. If you get confused about how to take readings or how to interpret them in code, check out some of the Base Kit projects like "Press Button to Turn on LED", which is a simple example of taking a reading from a button.
Don't forget that you can use the lcd.print() method to help you troubleshoot, too. If, for example you want to use a light reading to trigger the backlight, you can print the light reading to the screen as you carry the screen around, finding out what your local light readings are.
