    what i am trying to get:

    1.) an encoder/decoder that has at least 4 input/output
    2.) and output that is always active when input is still active ( what i mean is out will stay on if input is still on)
    3.) availability
    4.) the cheaper the better

    im making a spy toy car and this is the beginning of it thanks :D

    I have no idea...

    What do you want to encode and decode?
    What is your input?
    What does your output has to look like (voltage, current)

    -> a simple wire will do this.

    You need to be more specific and supply more information to get help from anybody here.

    i have said that i will make a spy toy car, this decoder will drive a servo to make it run, so this would include wireless modules and ICs like HTE/HTD... this is all info i can give for i have no more informations left :(

    Please forgive me. I'm in an ornery mood. What the hell is a HTE/HTC IC? I Googled it until my blood pressure started to rise. Is that Hyper Text Emulator/Hyper Text Control, what? I have no idea! I'm not even sure I know what a spy toy is. Anything that invades others privacy is not a toy.

    I'm still at a loss. A decoder needs something to decode. What is this? The position of the car? A signal from a transmitter? A barcode?

    A servo is not suited to drive a car. A servo is used to position an actuator. For movin a car you will need a motor and a gear box.

    Go to a hobbyist or toy shop and look for a kit to asssemble. The kit will contain the parts required and an instruction.

    hey Chris

    the OP typo'ed in his module description

    have a read here for HT12E and HT12D modules

    they are a very common method for encoding and decoding data to be sent by 315/433 MHz RF module links

    cheers

    Thanks Dave. Either I'm going blind or he posted that in another thread. I don't see it here.

    BTW, I damn near had a coronary reading the prices until I discovered I was reading Indian Rupees! :D

    i am worried that the output (lets say the decoder's output has led on it) will blink only once (for like less than a second or whatever) even though i am still pressing the encoder's input (lets say a push button). I dont know what it is called but i am trying to drive a servo to make a toy car run with a wireless controller with an encoder in it. Tell me if i'm wrong.

    It's not a Servo. Does this toy car currently have a receiver/controller installed?

    When you press a button, move a joystick, etc you're transmitting serial data to the receiver/decoder. So I'm clueless about your LED question.

    are my questions too stupid or your brains are too advanced? i believed i ask a very simple question.

    try to imagine a MOUSE BUTTON, if you PRESS it, does it execute many times? no. only once. and that is what im trying to ask if the encoder acts that way.

    and to answer your first question, im asking what IC that will fit my conditions to make a reciever and transmitter.

    In other words, you are asking us to go read the datasheet for you.
