-Macros are sections of code that are repeated a number of times within a program.<br />
+For an excellent introduction guide, we recommend [https://www.flowcode.co.uk/education/ Introduction to microcontroller programming]
-It is more efficient to use a macro than to create the code repeatedly every time it is needed.<br />
-For more information about macros, see [[What Is a Macro?]].
-This exercise shows how to use macros with a menu to create a simple LED flasher. The LED can be made to flash at different frequencies by pressing different switches.
-The first section looks at using 'Component Macros' to create the core timing sequence. The second section looks at using it to turn on a lamp for ten seconds once a switch is pressed.

-==The core timing sequence==
-At the core of the program is a section that sets up the LCD to display the time.<br />
-The flowchart sequence for displaying the elapsed time will be:
-::::* Initialize the LCD using the 'Start' macro.
-::::* Set the cursor position in the LCD, using the 'Cursor' macro.
