LED to power a DC motor

[kitcha]

Hi,

I am designing a circuit. It consists of two parts, the output of the
first part is an LED signal, which is ON/OFF based on certain
conditions. I require a DC motor to be powered on when the LED is in
ON state. Could you please suggest a suitable circuit for the same?

Thanks,

This is from the main system. & Me?

I see the LED light is "insyies" that means good stuff - but all the ideas
of
what it is to be a "GReen LED" light is wierd & very agressive in terms that
are untermable.

Green Light is used for conditionings - & usually "HID" inside of something
as its poweer is wonderful - but extensive in ideas of what
it is to be a things of the past.

Options F doesn't exist anymore as it is the ideas of what to what that
is the ideas of what IT is to be students in the centuries of Life its self.

No safety check for ME.! As this is YOIUR codes from the main
Networking - if you want to say they work, - inters-Thingyies. -

It's up to you as it goes & comes around. It's aplay Gamers Nightmare,
as it Goes & comes around in this thingy as it comes around - it still is in
.... This is Your clue supers Girls,

Worra lorra top-posting bollocks. OP wants to take maybe an ORP12 LDR, a
100k trimpot, and stick them in a base-bias configuration, adjust the
trimpot so that light from his first circuit's LED output switches on an
output cct tranny - maybe a BC107. Use this to darlington up to a 2N3055
or similar, and use the output to trigger a relay, switching on the motor.
Good grief, this is not difficult stuff!!!

Yeesh.
Pete.

What provides the signal to turn on the LED?

How big a DC motor do you need to control? What voltage and current?
DC motors come in sizes from pencil-eraser to locomotive.

It's not hard to do this, but we need more information?

4N25 optocoupler into BC337/25 with relay in collector cct with 15A
contacts. Relay into contactor - coil, voltage and contact current rating of
your choice.
-or-
DC motor hooked up to a switch, when you see the LED turn on, throw the
switch!

Might be possible to use a transistor. Connect base to LED and motor in collector circuit. Don't forget diode to protect transistor from back emf of motor.
This depends on choosing transistor capable of carrying the required current for the motor. Otherwise transistor drives relay, drives motor.
