Hey, thanks for the link in spanish
I remember we had one of those at school, you had to move it with your hand so you could view the text... then somebody made a motorized version of it
Buying list (prices in euros, to convert use google
)
-1 PIC16F628A (2,40-5[ch8364])
-18 pin socket (0,20[ch8364])
-7 high luminosity 5mm LEDs (preferably blue or green so you don't need to use resistors) (0,20-0,70[ch8364] each)
-2 battery holders (sorry, translated it as I could..) for button cells CR2032 (0,30 each plus the coin cell batts. at 0,50-2[ch8364] each)
-1 1K ohm resistor
-1 mini permanent switch
-1 piece of PCB
circuit scheme:
Ok, I translated this with google because I was too lazy to do it myself:
The most important issue is the source code with which we must set the PIC. It is written in PICBasic. Within the code file are instructions to add more phrases to the repertoire. I leave with you the attached file. Bas. To compile you must use a compiler PICBasic, as the PICBASIC. You can also use commercial software such as Microcode Studio (the latter is the one I use and is very very simple to use). The paste is that the program is worth a good money ... but if you "what you allow," "do with it."
Once compiled (in microcode pic16f628 just select from the list and make a button) you will file. Hex. This file you need in your program with a PIC programmer that may be the TE-20 or B-JDM (the JDM is not normal).
(If you don't wanna read it, it basically says you need to program the PIC controller with PICBasic).
finished project:
