Modern turn signal lights v2.0 for cars and trucks - Arduino, FastLED and WS2812B

[@Tarex_]

awesome projects, i love them, on my circuits i actually decided to drive brake lights on a separate red strip, but i have the luxury to hide it in the gap between the WS2812B strips when they are beside each other, i have one acrylic face over the whole setup

[@IonutFedaceag]

Thanks! Good idea, you reduced the overall cost and increased the visibility for the brake lights... Can we see it? :)

[@Tarex_]

Think small, build big! i haven't posted it yet, but i can show you videos with the old circuitry, if you write me on instagram or something @3dp_mini

[@IonutFedaceag]

Well, i would send you a message, but i don't have facebook or instagram account, because i don't agree on how the data is procesd and shared... Could you post the links here or send them to my email? Thanks! ;)

kzbin.info/www/bejne/jJ-Zp2hro9-EaNU Here i am using a Ws2812b external controller, just for testing function, that is from june, though after i burned out one of the strips and then got caught up with work i didn't continue, but here you can see the two separate LED strips

Hi thanks for the nice project. I have a plan to add led strip to my car but question is how i connect to the existing wire? For i. e. The one going to tail light/turn signal My understanding is thru optocoupler as shown in the video so do i need to replace each push button with individual optocoupler?

[@mechatronics2269]

Thanks for sharing such information brother. Your version is impressive.

How about 16 led lights for tail lights where the turn signal is knight rider?

[@coytimotoworks2440]

Nice one bro very nice

[@IonutFedaceag]

Thanks! :)

[@thomasalmeida3471]

I loved this version, but i’d like to make suggestions… first, the reverse lights would work better on the turn strips… i made the change but couldnt turn off Second: diferents led lengths.. it’s hard to fit the same amount of leds inside the lights… Thrid: the drl turns on with engine on, but not dimmerize with tail on… Forth: knight rider on Back turn strip… i made the change and worked, just have to copy the knight rider part and change “leds[0] and [1]” to “[2] and [3]” but make sure to change the drl color to 0,0,0, or you Will have a drl on the Back… they are in the same part on the code… Fifth: the knight rider does not overwrite the drl on… so the knight rider would only work with engine off… not a rider… Sixth: the brake could be a pattern you choose… i made this and think it worked, just changed the “full gradient” on brake parts to the same code of the tail model, with new variable, of Course, and made the brake as you can choose the pattern… Seventh: this is aesthetic, but i think CRGB(255,30,0) it’s a better orange for turn lights… Eighth: more patterns for show modes like rainbow and police lights… working on the drl and turn strips… I’d really liked the code and wanted to use in my car but it’s not the way i need, mainly because of the led lenghts This code it’s the ultimate code for rgb lights on cars, almost like the blue ghozt module… but i think i came late, he is not making vídeos anymore

[@skrachvynl]

Being designed for use on a car, does the cars flasher relay for the turn signals and hazard lights have to be eliminated? So you have straight power when turning on the switches for either and the arduino controls the flash time?

[@IonutFedaceag]

Well, i thought it so you don't need to remove the cars relay flasher. You can synchronize the signal with your car relay flasher in the code and you don't need straight power for the switches/signal.

[@MultiDjpollito]

Hello I like ur videos. Can u tell me the name of circuit or module u be used. Thanks u

[@IonutFedaceag]

Hi and thanks! I've used an arduino uno and ws2812b led strip, thats all. At the end of the video you will find the basic schematic. ;)

How if we use hpl led? Can we change the led with Hpl led?

[@IonutFedaceag]

What do you mean by " hpl led" ?

[@andrewerasmus5036]

Hi can you please explain connection of the Optocoupler.input from car to optocoupler ect please

[@andrewerasmus5036]

What im trying to understand is should each input have a optocoupler.like for the indicators.should there be a octocoupler for left and one for right?each with its own input from the car?

[@IonutFedaceag]

@@andrewerasmus5036 To put it more simpler each button must be replaced with an optocoupler... each input in the controller must have his own optocoupler...

Thank you.will this code work on a arduino nano?want to use only the rear light function.10 leds per indicator and 20 leds per brake/reverse/tail lights.so 60 leds in total.

Hi, your video was helpful for my oncoming project, but now i'm looking forward for a effect like when i startup my car, my DRL will take a full scan run through the whole line then slowly light up when finish scan run, it's like what you found in latest audi A8, can you program it? Thanks

[@tigerens666]

hi im new in arduino world i hawe a question can you draw aschematic if my triggers (buttons) are 12v and the led strips are also on 12 v(because they ar 6m long )

[@IonutFedaceag]

Hi, The schematic for using 12v as trigger is in the basic schematic for this clip (optocoupler). If you have led strips at 12v, this means that you have/use ws2811, but keep in mind that that the maxim voltage in a car is 14.4v while the engine is running and your led streaps will not last a long until they die... so i suggest to use ws2812b with a voltage regulator to step down the voltage to 5v... (or to 12v if you insist with ws2811).

[@arefinrony]

dose this work with ATTINY85 and Arduino Nano V3.0 ? and Arduino Pro Mini 5v 16MHz ? plz sir make a video about Optocoupler instead of button plz Ur vidos areso helpful thank u sir

[@IonutFedaceag]

For Attiny85 the sketch is to big, but with the Nano 5v an Pro Mini 5v should work ok! That will be my next clip, how to use optocouplers as inputs and outputs, i just need to find the time to make it! Thanks and with pleasure!

nvm heheh ty anyways.. my problem now is the optocoupler.. its not working, i put 1k ohms 1/4 watts resistor .. the 12v connection is ok while the 5v didnot switch on.

@@justinestardo8545 If you have the correct part number for the optocoupler, then respect the schematic and everything should work ok. Here is the datasheet for LTV817 - www.mouser.com/ds/2/239/LTV-817-827-847-647.pdf If you have another part number, then search the datasheet for your optocoupler and connect as is shown in the datasheet.

[@jcjanestardo1782]

Can i add bluetooth to this? So i can change the color any time of the drl and running light?

[@IonutFedaceag]

Yeap, but be careful with the bluetooth security, can be little tricky and very important.

[@jcjanestardo1782]

Boss how many leds in this set up? My step down only have 3a max.

[@IonutFedaceag]

@@jcjanestardo1782 Well, they are 6 strips x 20 leds per strip, in total 120 leds... if you have standard ws2812b with 60 leds per meter they consume about 60 mAmps per leds, so by my math you wil have a total consumption of 120 leds X 0.060mA = 7.2 Apms ...

I get the same error sometimes, i think is from FastLed library or Arduino ide, i don't know for sure, but after a restart everything works ok. I'm using Arduino ide v1.8.9 and FastLED library v.3.2.7.

[@dhm_kats]

thank you for this, and thanks for replying to me at your other video. so i used the code on your previous video for my scooter. as i am a total newb at these stuff, i didnt understand the reason of adding resistors or the other ones Ohm for the data pin the on the leds. i only used these images-na.ssl-images-amazon.com/images/I/41Qu5AP7bwL._SY355_.jpg as a way to decrease the ~12v of the scooter lights to 5v for the digital pin input. i power the board from the dc jack which is powered by the headlights. (12v) or something. when the turn indicator starts, the led freeze due to lack of power. i figured that out cause when usb is also connected to my laptop everything works fine, till the moment i start the motor of the scooter. Please paste a dontation address of BTC or anything convienient for you at this video and the next, i would like to tip you. Previous video and this video is of great help.

[@IonutFedaceag]

First of all, do not use linear regulators because they are not efficient, they can oscillate, they can overshoot the 5V limit and most important if for some reason you don't have the ground connected 12v will pass through it and kill your microcontroller. Just use a optocoupler is simpler and safer. You should never power the arduino from multiple power supplies (usb + 12v from the scooter), bad things can happen. The reason for the resistors at the data pin are for limiting the current, less strain on the transistors, longer the life. To power the leds and arduino i recommend you to use a step down buck converter, they are cheap, efficient and they can handle sufficient current. (the regulator from the arduino can't handle to much current - look up the data sheet of the microcontroller that you are using) I've updated the videos descriptions with the donation link and it will be much appreciated.
