Remote Switch

[Jag01]

Hi all,

Just a quick one, does anyone have a design for a circuit that would allow the switching of a reciever channel to an off or on state via the transmitter.

I want to be able to switch lights on or off from the transmitter

cheers,

jeff

USE an RX2/TX2 circuit... and CD4013 at the outputs.. to control ON-OFF

This page has links to several simple ones. Follow the links for R/C Switch.

Jeff,

please use the search function - this subject has been discussed time and time again - lots of circuits around from descrete component, PIC micro's or servo moding

Depending on the details of the application, it might be possible to use a small brushed speed control. There are some pretty cheap ones out there.

Here's one I pulled from a post about a month ago:

There are a few more interesting things if you go to the main site

A simple one ... also available as a kit !!!

Explanations are enough to realize it ...

The easiest and cheapest is using a servo amp board. Works really well on 5th channel that isn't proportional.

[Ralph Weaver]

The cheapest and easiest is to use a $10 5A brushed speed control.

[Acetronics]

Cheapest than a CD 4013 ?????????????

LOL !!!

If you can use a 4013 alone with no PCB, no resistors, no capacitors, no wires, no connectors, no power transistor, no labor, I'd like to see it. I can get a 5A GWS speed control for <$10 new. Probably less used or on EBay. Next time TBL.

The servo amp board would be easy, but you can't get many servos for <$10. And you'd still have to do some work.

1 x 12F675 and a small square of veroboard - total cost probably around £1.50 ($3)

This one was used for a cars break lights (and normal lighting) detecting when the throttle was moved quickly to reverse ( ie the pulse width changed to below 1.3ms the lights came on (fward only controller)

[Ralph Weaver]

A uC would also be my preference, but that assumes you have the development tools and knowledge. My need output transistor depending on current requirements.

[Malc C]

Its possible to drive a FET directly from the PIC. I used one to controll a 12v 55w car bulb !

I agree that if you wanted to write the code yourself etc then it takes a bit of time to learn whatever language you choose, however there are lots of examples and freely available HEX file available on the net, that you don't need to learn how to program them. And the hadware required to load the HEX to the PIC can be purchased for around $12 upwards

[Stef]

Adead servo that we all have is free a cheap live servo can be had for $4.80. Depending what you want to switch.

I programmed a PIC12F675 that does this function awhile back.
