Hi, any progress with this project?

I'm starting my own project.

Thanks!

Hi,
nice project you have.

Can you share your PCB schematics and components lists? I would like to try to build one too.

Thanks!

Hi,
I connect a simple nokia LCD to arduino and I can use it with simple functions.

I used a schematic like this:
http://www.amontec.com/lcd_nokia_3310.shtml
and
http://www.techdesign.be/projects/datasheet/nokia_3310_LCD.jpg

Modifying this:
int LCD_DC_PIN         =        2; //  PB0  4  Data Command
int LCD_CE_PIN         =        3; //  PB2  5  /CS   active low chip select ??
int SPI_MOSI_PIN       =        4; //  PB3  3  Serial   line
int LCD_RST_PIN        =        5; //  PB4  8   /RES RESET
int SPI_CLK_PIN        =        6; //  PB5  2  CLOCK

with my pin-out I was able to run this code:
http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1200398529/16#16

But i wanted to use this library
http://blog.thiseldo.co.uk/?p=383

That library is very powerful since it has lots of functions to draw,
but i'm not sure how to make it work without the LCD shield.

Any idea?

Thanks for your help!

For now i'm having 2 problems.
first: no multitask with arduino, I can switch tasks every 50 milisec but for complex tasks that doesn't work.
second: time, but i will build a RTC but i liked that idea. The problem is that I will need more than on alarm a day.
Morning and Evening at least. But that's a very good idea.

thanks for your advice.

I'm also making a fish feeder.
Could you please share your project? Hardware and software.

Thanks

That's a good question, I believe its 180, but I'm not sure.
Anyway, I already talked with the shop and I will replace them for other models.
By code, is anyway to make it run more smooth?

Description: Here is a simple, low-cost, high quality servo for all your mechatronic needs. Small servo with a standard 3 pin power, control cable, and mounting hardware. This servo is very similar in size and specifications to the Hitec HS-55.

Its a copy of Hitec HS-55

Hi all,
I just get my servos yesterday, I'm using the servo library to control them, but they only rotate about 150 degrees.
Any idea? Can it be solved with code?

Other problem I have is with control, they aren't very smooth, seams they are glitching.

Thanks for your help.

First I have to optimize the code, i belive i can get some free space, if not, maybe i will use one of this:

I2C EEPROM - 256kbit

thanks for your reply.
Well, thats bad news, i have to get other way, maybe with a SD card, but the problem is that I don't have free pins for SD card.

lets see...

Can't we just replace the chip with other but only with more available memory?

Thanks,
but i don't understande nothing on PDF, i don't know too mutch of electronics.

can you help me with pin out?

On my code I have:
#define RES   10 //pin10
#define SCE   9  //pin9
#define DC    8
#define SDI   7
#define SCK   6  //pin6

can you help how to change my pin connections so I will be able to use the same pins that shiled have to use the library.

Thanks!

Can you tell me witch pins are used by the shield?

imagine, something like this

LCD Pin 8 - RES - RESET ---------------------->Arduino pin 6

I wanted to use it with a standart LCD, not the shield, but i'm not sure how to config the pinout.

Thanks!

HI,
i'm also making a fish feeder, can you post some pictures or video from your project?

Thanks!
