That's fantastic!! Exactly what I needed for trailer!!

This would have a very piratical use in creating a wiring harness for a trailer. They sell for $150 to $200 US and do the same thing. This looks like a much more reasonable option and will protect the signal lighting in you car when hooking up a trailer. The days of just tapping into the lights for a trailer is gone with all new cars. This looks like a inexpensive alternative. Good stuff and WELL explained. Thanks.

That diagram visualizer website is badass. Definitely gonna use it on all my future projects.

Beautifully delivered presentation and project planning. My best tip for vehicle lighting cluster modification is to not bother... but if you do want to proceed dont hack apart your OEM units and purchase some non OEM aftermarket ones. Taking apart lighting can be tricky. Some are ultrasonic high frequently welded. Some are bonded with polyurethane. Dont forget that plastic is a thermoplastic and baking them in the oven can cause irreversible damage

Hi bud what a interesting vid thanks for sharing 👍

Hi Scott, great video as usual - keep them coming. Q - will the same Zener diode method work with 24V vehicle electrics?

Super !

Interesting stuff - thanks for the video. If I may make one comment on supply voltages... Automotive can be an engineer's nightmare. Cold-cranking can lower the 12V down to 6V or so in some cases. And beware the load-dump spikes. Solenoids and motors can throw all kinds of junk onto the 12V supply, and short spikes in excess of 50V are not unknown. So you did the right thing with your input clamps, but you should perhaps consider the supply regulators that they use (and their input capacitors or other filter protection) to avoid nasty surprises.

@ScottMarley

Thanks for the advice! I was reluctant to put too much capacitance on the power input, as I presumed that would delay the boot of the Arduino (I might be wrong here, I'm no expert!). Or are you saying to make sure that any components on the power input should be rated much higher than might otherwise be the case? Or some kind of choke perhaps on the power in? It was an interesting thing to look into and is just an experiment really, always happy to learn though!

@@ScottMarley I was basically trying to say that you need to ensure that the parts on the input have an adequate voltage rating. Specifically rated regulators are often rated with maximum input voltages up to 60V or so. They should not run like that normally (too much power loss) but they will not get destroyed by the spikes. Due to battery the voltage drop on cold starts, regulators with minimum voltage low drop may also be specified.

Hello, I was wondering what the setup would be for say an led matrix sequential for the turn signal?

Compliments on the video! It's a simple but detailed explaination. I was just wondering if it was possible to use a 5.5V, 0.33F or 0.47F super capacitor after the buck converter to keep the arduino running between the blinks so that a more complicated animation can run. Seen as I wanted to use about 64 leds in one blinker with an arduino, converter and capacitor each, I though 0.33F would be enough capacity to keep everything running. Does this work with the diodes you named D2 or D3 in your schematic? Just to confirm my thoughts... Also, if it worked, do I need to decrease the resistor you named R7 in your schematic because of the increased powerdraw of the charging capacitor?

Nice

regarding to the brake light. how to make it has 2 levels of lighting?like taillight + brakelight

Hi Scott your video is incredible well done and incredible informative I have already learned so many new things and have also started following the fast led basics and more on your channel. I understand the 5v1 Zener diodes and the schottky Diode to some degree but not where to extract/insert the signal wire to activate from indicator or brake. For a slightly different project I would like to replicate your circuit and have looked at schematics but struggling slightly to iterate how the flow runs on the actual hardware when connected to the car. In your example you still have the push buttons(just to show on desk) and then also included signal from the car. If I was to only use signal from the car those switches will come out but would I need to bridge the gap or put in something in its place that's the only part I don't quiet fully understand

@@ScottMarley thanks for your speedy reply. Again I am super impressed with how the video is done really well explained, just as I said got lost from where you built it on hardware and to putting in the car and doing the testing. Awesome to see it in action. I have a screenshot of your hardware setup. It's a little difficult to see where the vehicle wires are inserted but I bought all my components and have a buck converter so going to try replicate on my bread board and then follow schematic to see how it all runs and flows from input to arduino and then arduino to the led strip. Reading through some of these comments getting a little bit of extra insight like the one comment of on cold starts with voltage drop would that put any stress on the system. And Is there a way to overcome the voltage drop or at least not have it affect these components? Or do I need to relook at what components to use especially if longevity is in mind. Then on a slightly different note, how do you get an rgb strip to show the amber like in newer cars example like with Audi sequential indicators or do they use a strip with a dedicated amber. Ive Watched episode 2 of your fast led and again very informative but then makes me wonder If possible to get that color. I've been messing around on the CHSV and with CRGB to get there but it either goes more red or more yellow not getting that proper amber color with brightness

hey Scott how could I write this program in such a way that when indicator is pressed the pattern repeats for a certain time and shuts off after that time ?

Hi mate I know this is a bit of an old video but I was wondering if there would be any possible way of making the brake light section be like the taillights that are dim red when not braking and bright when braking I’m wanting to replace the rear windscreen middle taillight/brake light to something like that and also how would I go about that please and thank you

What if I have the input signal made for WS2812B leds and I want to convert it to regular signal for break light in a car lamp? Is it possible?

Nice. Question: Why not use 12volt LED strip and relay system for inputs? 12v coil on relay will handle auto voltage changes and SPDT can toggle between 5v and ground from nano to prevent float. What potential problems could this create?

@ScottMarley

3 жыл бұрын

You'd have to be careful regarding the voltage you are supplying to the strips remember when a car is running, the battery voltage is more like 14.5V with spikes well above this. 12V LED strips might be ok with this, or they might not, I haven't tried. You might have to put a buck / boost converter in front of the strips to give them a constant 12V. You could absolutely use relays for this, I just decided to go for all solid-state.

Hello. I have a different project, but I can't find a solution. Your video looks good. There are 2 different places where I get 12v energy. When the capacitor is connected to the place where I first get energy (mirror floor lighting), the vehicle cuts the energy. If I do not connect a capacitor to the 12v part I get from the signal, the sliding signal does not work properly. This goes to the 12v regulator I bought from two different places. I am waiting for your help.

Im looking into implementing this for my motorcycle as an addon to the existing lights. I was wondering, is there a way to do this same thing, but have the brake lights and the blinkers on the same strip? My idea was to have the lights red when braking and then when turning blink them, and when neither have them glow white or something that way im more visible. Along with that is there a way to have it change led colors in segments? So lets say for example that I have a single strip that runs around the motorcycle, and i want to change leds 1-20 red, the 21-50 white and so on. I believe there is with some modification to the code, I just want to make sure before I get too far.
