Hello not sure if this is a networking question but I'm thinking of using the 433mhz modules the cheap ones i bought from ebay but the Question is in order to keep the power down I just want to turn on and off some leds but to keep the power down I'm keeping the 328p chips in sleep mode and only to wake up from a Signal from the base station. So is it also possible to put the 433mhz to sleep is that possible? Another thing is it needs to go from first floor to third floor hallway does these modules can go that far? these are the ones i bought. 433Mhz WL RF Transmitter + Receiver Module Link Kit for Arduino/ARM/MCU Wireless | eBay
My last question is sense i got a 10 pack of the transmitters with receivers is it possible to use one transmitter and 10 receivers so i can send the signal to all of them at once?
Whats the Base Station?
You can transmit from one TX to as many receivers as you like , but if you power down the receivers to save power they wont receive anything.
Those cheap 433 modules are totally dumb, and have no capability to discriminate what they receive.
This means that you need some smarts in what is receiving the data, and Virtualwire or Radiohead are needed
and have to be running in the Arduino to sort out your data from everything else the receiver picks up.
Hello basically What I'm just trying to do is something Simple have one base station transmitter and 4 or 5 receivers. With the Receivers just turning on 3 leds that is all. and from the transmitter base station just sends a signal with a push of a button nothing else.
Could you provide a diagram of what you are trying to do?
433 Mhz receivers cant turn on anything by themselves.
There has to be some kind of intelligence after the receiver to decode the data coming from the receiver.
If all you want to do is light up some leds remotely, then there are better ways to do this rather than using Micros.
Have a look at using PT2262 / PT 2272 encoder , decoders.
i can do a hand drawing but wouldn't look good sense my hands shake a lot. I'm learning how to do fritzing program should be able to do something in a day.
All I'm asking is how can i get multiple 433mhz receivers to work together with 1 transmitter to transmit to them all at once just to turn on a led? that is what I'm trying to do.
That is certainly possible.
The transmitter can be a Uno and Tx module.
Each receiver can be a ProMini and Rx module, perhaps all running the same code, or running different code to do different things.
Look at the simple examples in the VirtualWire library for sending and receiving data. Once received, how you interpret a byte to do something LED related is pretty simple. https://www.pjrc.com/teensy/td_libs_VirtualWire.html http://www.airspayce.com/mikem/arduino/VirtualWire/
Hey Crossroads i have a question these are the [Modules](http://" 433Mhz WL RF Transmitter + Receiver Module Link Kit for Arduino/ARM/MCU Wireless | eBay") okay i have 10 sets of them. so if i use 1 of the transmitting ones and and say 5 of the receiving ones is it possible or do i have to sign some kind of address for each one to make it work so the transmitter not sure i never used these modules before but once. i can do 1 on 1 one transmit and one receiver but never attempted 1 transmit and 5 receivers before so I'm not sure.
Those cheap 433 Mhz modules are totally dumb.
They have no capacity for addressing or for anything.
The addressing has to be done by whatever is driving the transmitter, and the decoding is done by whatever you connect to the receivers data pin.
The normal method of using them is to have an Arduino or some other Microcontroller driving the Transmitter, and another Arduino or other Microcontroller connected to the receivers.
The Virtual Wire library or a similar library like RadioHead will be needed at both ends.
Thank you Crossroads that help me and Thank you Mauried for the information as well. I wasn't looking to address them I just ask if they needed to be addressable to make them work like other wireless modules out there sense i only tried them once. But crossroads help me out and i tried and they work so that solves my problem. Again thanks for the help roads.
