I am completely ignorant when it comes to circuit design (but can build them if designed by others), so I am looking for some assitance from a kind intelligent contributor can help me along.
I will try to give detail information of requirements so I can in return get simple and clear detailed cicruit instructions and parts list. (Please)
Application:
I would like to measure distance between two objects (car entering garage)
Note, this is not a parking distance sensor, but a guide to navigate the right placement when going in between tight objects below line of sight.
Requirements:
Measure distance and display output on 10 dot LED bar graph
Cheap and simple (I will need seven of each measure/output)
Options:
Option 1:
LEDs change colour as distance decreases (This can be done by simply having four green three amber and three red, but it would be cool if they worked this way: 10 lit – all 10 green, <7 lit – all 6 amber, < 4 lit all 3 red
Option 2: Last two dots to flash when only these two are lit, but be solid when more are lit. (Combined with above option, would be optimal)
Specifications:
Accuracy: Less than +/-0.5% (Or < +/- 0.5cm for 100cm range)
Maximum Distance:
Adjustable setout:
Adjustable distance range:
Real time response (i.e. no calculated output, purely electrically activated)
I hope someone can help me out, I would appreciate any assistance at all.
