+#### Altera based projects
+
+* **VGA** - output via VGA interfact to motinors. Can draw multy line text with specific fonts.
 * **led4_highreg** - 12 LED circle sequence
-* **timer** - count down timer with ability set timer time. 
+* **timer** - onboard digital LED count down timer with ability set timer time. 
 Digital LED and Keys used for I/O.
