Hey Guys. I'm trying to hook up an analog sensor to the raspberry and since that won't work I was thinking about using the Arduino to do it for the raspberry. I know you can get an MCP3008 or something like that but I don't have it here, and it costs like 6 euro here, in the NL, 7 euro's more to ship it...
Would it be possible to use the Arduino like an MCP3008 and let it send the analog signals to the Raspberry?
Why should I need 64 pins? This is a 4*4*4 led cube, which means 4*4 = 16 pins, div 8 so 2 shift registers. My questions is simple, should I use another shift register for the 4 ground layer or should I just connect them directly to the Arduino.
I'm building a led cube of 4x4x4 and I'm trying to use shift registers, 74HCT595N. Now I have 8 port per shift register so I would need 2 for the 16 points of the leds. But should I use another one for the negative layers / plane layers of the cube?
Thanks I'm not that big of a pro in the LCD thing, the main thing for playing with it was to build my own obduino but since that sys can't work with the GDM1602a I decided to just order another display from sparkfun.
Which is atm still on my to-do list...
Here's the vid link, soz again for the bad quality, just skip ahead to about 1 minute.
the backlight wont go on so i went on and tried to see if i could get something on the screen anyway.
Second thing is after googling some more I found a second datasheet. on this one it says Built-in controller (S6A0069 or equivalent) in stead of KS0066U or Equivalent. Both sheets being from XIAMEN, on my LCD there is ver2.0 printed, now comes the greatest part this isn't mentioned in the datasheets
