Hey,
I am having some serious Problems with my APA102 Led Strip, Teensy 3.2 and Prop Shield. I hope you can help me!
So I have a Led Strip with 120 Leds and I have my Teensy and Prop Shield hooked up to it. I have a Code running on the Teensy that just turns the first 30 Leds blue. But after some time (usually around 5-15 secounds) it starts getting crazy. All the Leds start to flash randomly and then suddenly the whole thing just turns off. I power the Leds with a 5V power supply and the Teensy with my Laptop via Micro USB.
Thanks,
Kindest Regards,
Florian
We need a lot more information.
How have you wired it up?
Do you have a common ground between powersupply and Arduino.
What size is your decoupling capacitor and resistor?
Hey, thanks for your quick answer!
I just wired the Prop Shield GND to LED strip GND, LED_CLK to Led Strip CLK, LED_DAT to Led Strip DI, 5V to Led Strip Vcc, and that is about it. The Teensy, that sits on top of the Prop Shield ist powered with a Micro Usb Cable coming from my Laptop.
Thanks,
Florian

Words don't really cut it when it comes to wiring connections.
If those words are accurate, and I doubt it, you have not connected the 5V ground to the rest of the system.
It does sound like you are trying to take too much current through a regulator and it is overheating.
Hey, thank you so much for your answer! I used my Lab Power Supply for testing and it did work. It drew over 2 A so...
