Checking Program Length.

As programs become complex it is possible the micro-controller will run out of memory to store the
program. Check the previous program length by clicking the ‘Syntax Check’ button.

If there are no programming errors the Success window will open and show the amount of memory used

by the program.

To play all 4 songs and flash both lights,
this program used 32 bytes out of 256 or
12.5% of the total memory. Remove the ‘2
Snap’ on U8 (S-Out or Pin 0) and connect
the red programming wire. Download this
program. Then reconnect the ‘2 Snap’ and
run the program.

The fact that four ‘Play’ commands are followed by four ‘Wait’ commands indicates this program could
use variables and a ‘for … next’ loop. The ‘for … next’ loop does not have a standard flowchart box but
can still be programmed using the flowchart system as shown on the next page.
