How to make a simple 1 channel Remote control? Answered

Hey guys,

Basically I need to make a single channel RC, all it has to do it turn a light bulb on at the other end.

I have got the transmitter and receiver ( VY48C 433MHz Tx/Rx Pair). my electronics knowledge is pretty basic, I need a decent diagram to follow, it would need to have the resistor values on it as well as the names of the other bits I need. the light it is going to be use for is a simple household 9V bulb, the range needs to be up to 10M. It is just an on off switch RC so please keep it basic as I am on a tight budget. Please don't tell me it would be cheaper and easier to hack a toy, I know that and have done it all before but this is to be used in a theater show so mush be a custom build.

Also I need to get this done by next week.

Thanks all

If you'd had longer and didn't have to have it done by this weekend I'd have suggested some of the radio stuff from Ciseco. I've been playing with it this week and it's dead easy.

One of these:

And two of these:

Would have you up and running in minutes. Probably not the cheapest option though.

You'll also need an FTDI interface to program them, but if you're talking to Steve about programming microcontrollers it's likely you have that.

They transmit/receive a serial stream from one to the other. You'll need to do something similar, perhaps using a 555 time to generate 1kHz tones, and play them into the transmitter. At the other end, you can decode the tone and use that to trigger your lamp. Use an LM567 as the decoder.

Not dead simple I'm afraid.

I was reading up on the circuit I would need to make and it was saying to use a standard push button switch to turn the lamp on and off, could I just use that method? Also would I need to use a encoder and decoder? do you have any schematics I could follow?

Tanks for a quick response! :)
