LED Ring Madness on GPIO13 MOSI ESP8266

Other Hardware LEDs and Multiplexing

hi im in deep troubel

i designes asmall board Milled it and got it solderd and programmed

ALL GOOD

as ESP8266 has less GPIO i did connect the FOR ME Most unspectacular item LED ring to MOSI GPIO13 and configured it

 pinMode(LEDPIN, OUTPUT);

 pinMode(trigPin, OUTPUT); // Pins werden deklariert

pinMode(VRechoPin, INPUT);

pinMode(HRechoPin, INPUT);

pinMode(VLechoPin, INPUT);

pinMode(HLechoPin, INPUT);

digitalWrite(LEDPIN, LOW); // GPIO 13 MOSI as output

Serial.begin (9600); // Im Serialmonitor die Baudrate auf 9600 einstellen

so it WORKES for about 10seconds then the led going MAD in Brightness and color!

i did solder a 10uF Tantal to LED Ring 5V GND but nthing

when i Touch the 5V and GND with the meter the FUNCTION is back for 10 sec then it goes MAD again

WHAT can i DO

USB powerd D1 WEMOS Shield

What kind of LED ring? How many LEDs?

What is happening is not that uncommon. The proper procedure is to prototype before making boards. That tends to eliminate this type of problem.

Without an annotated schematic we can only guess. Try it with one LED and if it works that indicates your LED ring is bad (99% sure it is drawing more power then you can supply. The port pin can only drive one or two LEDs. The Recommended current is a max 12 mA with an Absolute max: ~15 mA. The total for the chip is about 50mA.

Recommendation is to post an annotated schematic so we can answer your question in place of guessing.

GOT it Solved !!
it has been s stack overflow in DATA of the FASTLED
MY fault wars continios overriding the LED's no clearence
so i did fastled.claer();
now it flashes within 2ms but it Workes proper

SORRY for this not along the rule programming clear and redefine data at every loop on fastled !!
