I am trying to add LEDs to my scooter project I recently finished! Well I did already, and they all worked great, but now im having issues. I decided to add a strip of 5 LEDs right behind the display, and a strip of 5 on the tail. When I first coded it, both strips functioned correctly according to my code. I moved the scooter after programming, and the tail light shut off!
I have now tried re-coding it, replacing that strip, replacing the other strip, replacing the wire, etc. with no luck! What could be the problem!? This doesnt make any sense .
My guess is either your flux capacitor is failing to reach the proper frequency, the dynamometer is picking up noise, or you need to show us your code and schematic so we can better help you.
Ummm, my code is ~1200 lines long . I can share a schematic and my code though if that'll help. Also, all my code is non-blocking so it was a bit more complicated than just using "delay"s.
No, I am positive its the thimagig on the whatchamacallit, I saw the flux capacitor laying by the back porch. The OP just got a sample of what transients can do on vehicles. The power systems are very nasty. If he posts an annotated schematic showing what he did including all power sources that would help. Also the OP needs to post links to technical information on all of the hardware devices.

You can grade me on my code organization if you like .
All the other info pertaining to parts (their links) and all other things are in my tutorial here:
I hope this is enough info for some help on pin-pointing the problem!
Edit:
Also, I do have an oscilloscope and I did get these photos of the signal, one before the first strip and the other right after, but I'm not sure what i'm looking at .
Nice Schematic! I am looking at a way the motor transients can get into the MCU and its circuits. Can you post a link to the DC/DC converter. Also between R1 and R2 I would add a capacitor a few hundred nF. That is a way a transient can not get in and the capacitance will not hurt your measurement. I would also modify the touch sensor so it goes through a resistor before going to the micro to protect it from transients. I do not see any pull up resistors on the I2C bus lines, they should be around 3K3. Only one pair. They may have some in the modules you have connected, I do not know. Getting consistent scans with the I2C scanner will confirm it is all OK.
I am quite sure they do, although I can check again to make sure.
Thanks! What do you think of my code organization? It’s quite lengthy, so I was trying to be as neat as possible… and I just learned about non-blocking code! So this was my first real skills test on that lol.
That makes sense! FYI though, the motor is completely un-attached at the moment and has been since I started adding the LEDs; every motor driver I try keeps blowing (I’ve tried 7 so far ). I have not tested the LEDs with the scooter itself actually driving.
What motor driver and how is it attached to the system. Those can get expensive and should not be blowing. Add links for both. Sleep time for me so I will check tomorrow.
So actually, that makes six dead, and going to order my seventh rn. The one I think I should order is:
or this one:
#1 worked the longest, but then just stopped; both of them #2 worked the best! Way better speed and torque than #1, but it stopped working really quickly. The second one, I literally soldered everything up, and turned it on, and the motor spooled up way past full speed instantly; so fast, in fact, centrifugal force alone pulled the tire off of the wheel!
I don't remember exactly what happened with #3 and #4, but im pretty sure they worked for a little, and then just wouldn't work.
With all of these, when they stopped working, the wheel would not spin freely very well FYI, like it was being resisted.
Do you have any ideas on a better one to buy?
Edit:
The connections are very simple for me... they're pretty much stupid proof lol. I wire the 3 phases of the motor to the motor driver, along with the 5 hall wires (2 are power, 3 are phase). Then 36V to + and GND to -, speed input to the ESP32, and thats pretty much it. I haven't tried any other features like braking or enable (haha, maybe I did try "breaking").
Oh, I also forgot to mention I tried removing the first LED strip, and wiring the data signal directly to the second strip instead, and I got nothing still. I also tried using a different wire for the GND (instead of the shield of the 16/4 cable) just in case the signal was accidentally being grounded. No luck.
Soooo... that voltage regulator I bought off of amazon is outputting 5.33V instead of the advertised 5.0V. I looked up the max voltage for the WS2812 LEDs, and it is 5.3V! So, the voltage regulator was just frying my strips .
Any ideas on how to lower the voltage by 0.33V? Diodes in series? Im pretty sure a LDO wouldn't work for such a small amount .
.
. I can share a schematic and my code though if that'll help. Also, all my code is non-blocking so it was a bit more complicated than just using "delay"s.
.
