Hey.
I still have my Arduino v card and am looking to loose it on a head motion controller fpv conversion of an me262 jet.....
One of the things I want to do is have a gauge that displays flap position like this pic.
The led bargraph are too big for the cockpit without lookin stupid....
I want to make it out of 0402 smd LEDs if I can get them tight enough to fit inside a gauge molded into 3d printed dash. If not q0603 smd leds. But the resistor thing confuses the hell out of me... I get the concept, but when I go to buy what I think I need alliexpress has it written I ways i don't understand . So to make things easier I thought I would ask a little help. Firstly this is the data for the LEDs I'm looking at.
0402
YELLOW
Volume MM: 0402 1.00.5
Brightness MCD: 80-100
Voltage V: 2.0-2.2
Current MA: 15-20
WHITE
Volume MM: 0402 1.00.5
Brightness MCD: 200-300
Voltage V: 3.0-3.2
Current MA: 15-20
Color temperature K: 6000-8000
YELLOW GREEN
Volume MM: 0402 1.0*0.5
Brightness MCD: 50-80
Voltage V: 2.0-2.2
Current MA: 15-20
Or
0603
(Color) (V). (mcd). (mA). (View°)
-YELLOW. 2-2.2. 100-200. 20ma. 120°
-WHITE
-YELLOW 2-2.2 50-80. 20ma. 120°
GREEN
-RED. 2-2.2. 100-200. 20ma. 120°
I've decided I prob b using the position of the servo like a potentiometer as a reading to update the Leds in my flap position bargraph...
Any sugestions on the best way to do that because getting a servo that has the extra wire and outputs it's position. Cause yes I can do that, but if there's something I can add onto a servo to make it work I may do that
Also anyone have any good ideas on how to hav a red light activated while gear is up and q green one when it's down?
A few different things have been thrown around like photosensitive ir that the legs would break the beam of and be the switch. Also limit switches, could alsouse the same premis as the flaps with servo potentiometer.....
I more thing, should I power it seperate to the planes.power?
Whats your best ideas an advice before I pop my Arduino cherry..... Thanks guys, sorry to ask so much of U guys on my first msg. But don't worry, I have other things reflex gun sight, what sensors are best to use, making pitot tube etc... Lol
Thanks guys and gals
