LEDs I was gonna power them with individual relays to Left and Right. How are these connected to the Arduino inputs i.e. The turn signal switches on the steering column.
SEQUENTIAL TURN SIGNALS SERIAL
Note that most Arduinos will reset each time you open the serial monitor window. All the output your sketch writes to the serial port will be displayed in the serial monitor window. You can print variables as well as fixed strings - look at the documentation for Serial.print and Serial.println.Īfter you have uploaded your sketch, open the serial monitor window in the IDE.
SEQUENTIAL TURN SIGNALS CODE
Insert these print statements at points in your code which tell you what the sketch is doing and why. In the remainder of the code, add calls to Serial.println("Your message here") to send a text message to the serial port. You initialise the serial port by a call to Serial.begin(9600) you do this once, within setup(). The hardware serial port can be used to connect to a wide variety of devices, but it's particularly useful as a debugging aid. I was under the undestanding that serial port was only for LCDs, can I get a link for the serial port usage? The 'blink without delay' is a simple example of a non-blocking sketch. Instead of using blocking code which waits for each flash sequence to complete before it re-reads the switch input, you would use a non-blocking approach to poll the switch and turn the lamps on and off as required. You don't need to fix it to get the solution working, but the fix would be to change the overall structure of the code. Int right3 = 7 //LED 3 for right signal indicator Int right2 = 6 //LED 2 for right signal indicator Int right1 = 5 //LED 1 for right signal indicator Int left3 = 4 //LED 3 for left signal indicator Int left2 = 3 //LED 2 for left signal indicator Int left1 = 2 //LED 1 for left signal indicator I can get it to work of I only program one Turn Signal, but I need both. When I send it, it works for a second and nothing. Actually I think that one device (per side) covers it, so you could probably get away with just doing it with hand-modified wiring.I'm trying to make a Sequential Turn Signal for my 1955 Buick, I'm looking to put these onto the front fenders where the car has ports which are only there for looks. Basically, for each half, it'd look like rerouting the stock lamp to the "High mounted stop lamp" positive, then putting a suitably-sized P-MOS on the S&T positive, with gate attached to "stop." That way, the S&T line, fed to the new blinker, can only turn on if the brake lights AREN'T. Then, you unplug the stock tail lights and plug those into the "stop" signal only, and run "Turn L"/"Turn R" to the respective new-euro-spec signal lamps. It'd take an annoying number of connectors and harnessing, but I COULD whip up a control box that consumed "Stop," "Stop & Turn L," and "Stop & Turn R" to render "Stop," "Turn L," and "Turn R" output signals. The two outboard lamps get a "Stop & Turn" signal, but the center "high mounted stop lamp" obviously only comes on during braking. It would be interesting if someone in Europe could take a look.īut I think it's still doable at higher cost and complexity as long as the mechanical fitment works. So I'm still going to say no: the animated turn signals would require additional wiring and/or ECU reprogramming. Behind it is the taillight plug, along with another 6-pin plug that's for the trailer harness. There's a panel you can pop open under the 12v outlet in the back, on the left side. It doesn't look like there's a light sensor, it just runs the taillight signal back to the ECU so it's kinda pointless with LED taillights. Telltale is feedback from the stop/turn lamp I believe US regs require a signal if the taillight is out (the "fast blinker" that meant an incandescent bulb was out). As far as I can tell, tail lamp is for when the headlights are on, and stop/turn are used for those functions. The US taillights have 4 pins: tail lamp, stop & turn lamp, telltale, and ground.
SEQUENTIAL TURN SIGNALS MANUAL
I had a subscription to the shop manual for looking at some other things, so I looked at the wiring diagram.
