[SOLVED] Wiring Help #238

Closed david-bour closed 4 years ago

david-bour commented 4 years ago

Description I'll admit that I'm a bit of a beginner when it comes to circuits. Here's my setup below. I had a 150 LED W2812 to which I cut 113 out , leaving me with 37 LEDS. I had a level converter there just in case I needed it, but didn't use it. The application and LEDs are working but it seems to mostly "react" on the first 10 or so LEDs while everything on gets modified once in awhile. ESp8266

In case the image isn't clear, the ESP8266 is powered through a USB from my computer and the LEDs from a variable power supply set to 5V.

I can't help but wonder if my circuits are incorrect since I'm getting erratic behaviors with the LED instead of the smooth animations I see in the demo videos.

Likely a grounding issue, try connecting the wemos gnd to powersupply gnd

It was definitely a grounding issue. Thanks @SealedJoy
