hey

I was planing to build a robot with arduino mega for my project.

it shold do 3 main tasks. line following,obstical ditecting,arrow following

but my they are saying that i cant u any developed board like arduno..

but for my project i need arround 12-16 analog inputs.(ir sensors,compass,sonar)

1)can any one tell me what chip shoud i choose or how can i make a board like arduno for my work?(i was thinking to use 2560 inbult adc)

2)also need help with detecting arrows.

thanks.
plz reply soon

What is an arrow?

Are we talking about actual arrows? Like, cardboard or paper or something?

ADC’s --you need a multiplexer (or a few of them). Hit the Arduino website and search “multiplexer”. The chip, wiring and code are all there.

So many Analog’s?

Hey Roshan :slight_smile:

I’m thinking a Mega with it’s 16 Analog ports will be more than enough for your needs.

Also if you need to free up some Analog’s, IR sensors for line following can be made to be readable from a digital port with a simple RC circuit, You charge up the capacitor then time how long it takes the port to go low. A good example is the Pololu QTR8 Array.

And a Compass could also be connect to any of the 4 serials or I2C ports, depending on what type you buy.

Hope this helps a little.

Hey thanks every one
What I ment by arrow is there will black color arrow shape drownings will be on the floor. My robo need to detect them follow.
Other thin I cannot use Ardiuno or any developed boards
Can any one suggest me a good chip for this.
Thanks

Can you use the chipset?

Can you design your own board based on a chipset from a developed board?

eg. Buying a Amtel atmega1284P, Bootloading it, building the circuit etc?

Hi skip
Yes I can use my own one. But I don’t know how to make it.
If u can sen me a link or any help that ll b Great.

It doesn’t matter pic even.what I want is I need to keep microchip on robo while am progaming. It’s better if I can get output to
Monitor while developing.
Btw am using i2c interface
Thanks for helping out.

Google came up with this

http://maniacbug.wordpress.com/2011/11/27/arduino-on-atmega1284p-4/

 

It’s got a few links and a blog about a guy building a circuit on the 1284P.

Hope it helps

Hey
lets say if I made this will work like real arduno. I mean the cording and other things.
am not familiar with that blog. Dose anyone here have made it?
Just asking.
Anyway thanks lot.
That help means lot to me.
