Here is a present for Mike K8LH because of his help giving to signboard lovers.
This project Named LED mini signboard.
Features
*User define message (String length = 30 letters including spaces)
*50 different characters = A-Z, 0-9 & special characters
*Battery power operation 3.6V-4.8V
This is the smallest signboard I have ever made. The nice thing with this design is you can write your own message using its two buttons.
Saving is pretty simple
Press & hold the “Select” button at anytime. It will show you letter “A”. Now release the button. At each press the “Select” button it will shift to next character.
Press “Save” button to mark the selected letter. Likewise make a sentence by the two buttons & after completing press & hold the “Save” button for 4 seconds so it will save the whole sentence in the memory. Release the button now it will scroll the message nicely that you saved.
Supportable characters
Letters
A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z SPACE
Numbers
1, 2, 3, 4, 5, 6, 7, 8, 9
Special
“/” “%” “Heart” “Face” “-““=” “Comma” “Arrow” “+” “:” “Dot” “(““)””Degree”
