Hi,

more details please

Thank for reply. 

 

I need to do a project. A transmitter (small in size: maybe 4CM X 2CM)- send the data to the receiver (small in size too) and the receiver will activate the light. Distance: within 10m. 

 

Your prompty reply will be much appreciated.

light means fire? or electric light

if its electric light then it is very easy. you can use IR remote control and sensor thats all

press a button from remote – sensor will sense the signal – sensor will ON/OFF light using relay.

you will get several such circuits on this site

Or if you need RF communication, use 433mhz RF transmitter/receiver modules.

In your case there is no need for a microcontroller. Give logic high voltage on the data input pin of transciever and on the receiver the data output pin will become high. Connect your light source to the data output pin of receiver using a transistor switch.

Thanks for your reply. 

 

But there is a problem- i need a mircocontroller to manually activate the light. 

 

Is that any manufacturer of this? what “title” should i use to make enquiry? 

 

Thanks again.
