−
*'''Q:How to use multiple screens at the same time?'''
 
−
**A：In the next page [[Open Source LED Dot Matrix]], there will be specific introduction of the cascade of multiple [[Microduino-Dot Matrix Clock]].
 
−
*'''Q:Why does it display incompletely after counting to 20?'''
 
−
**A：Because the dot matrix resolution is only 8*8, there are not enough pixels, and the screen can’t display the numbers after 20 completely.
