Remote Controller

I need to prepare a remote controller with more than 20 functions, Is it possible to help me know?

Remote Controller

what is your background?
do you know
electronics
microcontroller
programing

if yes please specify the technology you are familiar with so that help can be provided.
your request is too general

I think it will be easier if you use general remote control. Then try to find what kind of data that modulate from the remote. You can decide the function in the receiver with microcontroller.

General remotes, such as: television, DVD player use infra red modulation; and they have many button to be choose (more than 20). Usually, they use infra red modulation or RF.

Re: Remote Controller

hi, you can use 9148/9149 (couple transmiter/ receiver in infrad.)

Thank you,

a remote controller with antenna with about 300m range is possible?

300m?

You will have to use RF range, take a look at this link, you may find it useful.

Re: Remote Controller

if u want farther distance you can use remote in RF: PT2262/PT2272 (receiver/transmiter)

Re: Remote Controller

Hi

i also build one by hacking one remote controled small car when i was not familiar with rf device.

There 4 key available but 16 key can be made by using some simple digital circuit.

Re: Remote Controller

If want to create this remote controller.You have to follow this step

1. Collect one remote controlled small toy car.

2. Open car & remote bring out both remote & receiving circuit.

3. Think about different working mechanism of this circuit.
This is easy.May be same ic used in both receiving & remote module.
(I cannot supply you any circuit diagram because circuit varies for different car
)
N.B.: If you want to make a 4 keys remote then you need not open or modify
remote circuit.

4. I use some D-flip flop(ic4013) with receiving circuit to perform switching.You can also use any microcontrollers to make it more functional.


(I add a pdf from kitsrus where rf module use to do this. This documentation help me most)

Thank you all, my biggest problem is that i need a 20 function remote controller by antenna...
