modul dotmatrix 16x8pixel (12x6cm)

Module Dotmatrix 15x9cm (display 12x6cm)

Step 1: Prepare Part

part list :

Universal PCB hole 15x9cm  you can purchase at PCBway :-)

2 pcs Dotmatrix 8x8  (sixe 6x6cm)

IC atmega16

DC soket

7805

Step 2: start to put the parts

put two display near top.. so we have space (about 9cm - 6 cm = 3 cm) to put such as button.. and DC input soket

use female socket to rise up the dotmatrix, it's also helpfull when you want remove or replace easily the dotmatrix when use socket.

hmm what the next ?.  to be continued

Step 3: coding...

now the soft parts..    write the code...     my laptop ready to run avrstudio  avr-gcc also arduinoIDE hmm which one?

starting ask Google ...  i found the usefull apk here the snapshot :

define port connection..

just direct connection that PortB connected to RowCommon,     PortC connected to ColoumPin 1st DOtmatrix,   also PortD  connected to ColoumPin 2nd Dotmatrix
