sooooo. I am looking for a down and dirty solution to use one of these link sets to operate as a button. Just a single wireless pulse without an arduino or floating voltages…

I have one of these

I am using it in a pov poi project. example:

I intend to replace the tac buttons on the pixel ion boards with a reciever. Then with one press of a remote I can sync and change

found one youtube video that did this on a breadboard, but unfortunately it had a pwm effect that made the led (was just an example) stay on but dim.

It’s not that simple. On the transmitter side you need an encoder. You can use a 555 timer
or (better) a HT12E
However, I would use a Trinket.

On the receiver side you need to decode the signal again. You can use a HT12D or the Ion Board. Make sure you transmit and receive with the correct baud rate.

For a really quick and dirty solution get yourself a RF relay. Check out what components they are using :wink:

I’m also start playing with theese 433Mhz boards.
Just a basic question… When using a arduino with the receiver it should be possible to receive signals from several transmitter (transmitting different codes)?

as long as it is the same freq. i believe so.

Consider also whether this “pre-made button” might be a good option? +

@Mark_Kriegsman yep, that’s just as the last two links of my comment. All on board, no headaches :wink:

Decided to go with an set of encoders/decoders ICs. Ht12d/ht12e. Please keep this open though. I am prototyping a product. When this one is finished I I’ll still need to figure my most cost effective and simple way. I just need the switch to wirelessly go high then stop when i release. So when i press start sequence they start simultaneously. The encoders/decoders will allow me to not trigger all sets too.

@D_Rob I did not understand what you mean with “will allow me to not trigger all sets”. If you mean with “sets” the light sticks you should be fine: On the HT12 you got 8 pins for address pairing (=256 possibilities) and make two or more receivers do the same. Please try this out. Then there are 4 bit data. The 4 pins on the encoder (AD08-11) correspond with the 4 pins on the decoder (D08-11). On the Ion you only got 1 button pin; connect this with a pullup to e.g. D08 and it should work.

Have a look to HC11 433MHz Wireless Serial Port Module wich can act as a wireless 3 buttons remote.
