y is the code written in void setup not in void loop?

thank you groove

thank you groove. appreciate your help
can you write me a sample code on what you said !! i'm new on the arduino ?

hello,

i used the servo library and it works fine!
i tried to analyse the code in wich was written i didnt get it!!!
so i need a sample code for driving a servo ??
something wich i could understand easily using for loops and delays only !.

thanks alot , appreciate your help.

thanks alphabeta i will soon modify it.

yep the pins are selectable you just have to define an array and send it
for example int a[]={5,6,7,8,9,4,3}
sevenSegment n(a); // thats for selecting the pins

hello,
i just made a new nice and simple seven segment library, you could find it at my website by clicking on the link below and downloading the new sevensegment library.

i need to know a small tutorial using the xbee, if anyone could send me one ? where do i buy it and how does it come ? is it in a shield or how ? are their any libraries asociated with it ?

insted of switches use digital arduino pins connected to ht12e ?
can this be done ?

hey,

yes their is a more cheap and good  way of doing this.
just buy a tlp434a(radio frequency 434Mhz transmitter),rlp434(reciever), connect it to the arduino and begin sending data and recieving via serial.
off course the arduino will be also connected to an lcd using the 4bit library interface .

good luck

i think mr.grumpy_mike you have to use google and read the data sheet!

what i mean is that if you read mr.grumpy_miker the data sheet of the ht-12e encoder you will find that the logic levels are
as the data sheet says :

"Error: AD8~AD11 pins input voltage > VDD+0.3V"

yes thank you for the reply but, can i send logic 5 and 0 volts to the rf encoder data inputs?
tha data sheet says their are certain logic levels that i could use!

i want to connect the ht-12e rf encoder data inputs to the arduino?
i havnt test it yet but in the data sheet it says that data input must stay either left floating or grounded, so is it normal to connect the data inputs directly to 4 digital pins of the arduio and send high and low signal to transmitt data? thank you.

hello, i need to know how to connet the arduino to a 3x4 keypad?
i've downladed the library from the playground!

what i need is a sourcecode example about setting the rows and colums not as deaffault, i want have for ex 3,column 1
4 columnt 2
....
so anyone could help and give some schematics about the connection
