Automatic LED turn on and off circuit, can someone check my circuit to see if it will work? Answered
So I'm working on project where I want LED strips to turn on and off depending on whether or not the IR LED and phototransistor circuit is open or closed
This is what I've come up with. Can someone please check and tell me if this will work or not (sorry I can't seem to find a good simulator)
It makes sense to me.
The power supply will be one of those 12V LED power supplies.
I will use http://www.ebay.co.uk/itm/LM2596-Power-supply-module-adjustable-DC-DC-Step-down-1-5V-5V-12V-24V-/261512603010
this to step down the voltage to 5V for the IR LED.
The LED strip will probably be this one
3 sections of 1metre long strips
In the images below, I've shown what I want it to do
EDIT: I changed the circuit a bit
