Set up a variable called "Count" as an 'Int' type. Double-click on the Calculation icon. In the 'Calculations:' text box type "Count = Count + 1". This will add 1 to the value of variable count every time the icon is executed. # Next drag another Component Macro into the Loop. Double-click the Component Macro and find 'Cursor' under the 'LCD' macros and enter '0,1' in the parameters. This will position the cursor on the first character of the second line. # Next drag another Component Macro onto the workspace and do the same but select 'PrintNumber' instead and enter "Count" as the parameters. # Next drag a Delay icon into the program and set the delay to 10ms or a hundredth of a second. # Go over the program and click on each icon entering comments on what each icon does. This seems like a lot of effort, but if you can discipline yourself to entering comments you will save time in the long run as your programs will be easier to read. # Run the program. You have now made a counter that will count (approximately) the time elapsed in hundredths of seconds.  (:nl:)(:table style="clear:both":)
