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&/project/share/#39;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
