I recently purchased a new car and started parking it in the garage. The only problem is that I have a hard time telling if I have pulled far enough in to shut the garage door. I want to use an IR trip wire with a visible LED to tell if I have pulled in far enough. have done some research and found that using the LEDs from a remote firing at an IR sensor will be my best bet. I already have a 5V power supply from an old phone charger that I am going to use. I am really new to designing my own circuits, but I do have some experience with soldering and following diagrams.
Wiring the LED is simple enough. Just a power supply, an oscillator, a resistor, and an IR LED
Wiring the receiver is where I am confused. I know that I will need various resistors and transistors in the circuit. I am imagining something like this assuming everything is properly powered and grounded: the output pin of the receiver is wired to a transistor/relay that sends power to a visible light LED. Would this work?
My question: What type of transistor or relay do I need to use to make the visible light LED light up? And does this schematic sound correct?
I don't want to use any microcontrollers or anything that needs programmed. This is a really simple thing to design, I just don't want to mess anything up.
