Question

ADAFRUIT DOTSTAR LEDS RELATED

I bought two different LEDs from Adafruit because I thought my first one was faulty. The Adafruit Dotstar 30 LED strip. One of the LED strips has the 4 input pins on one side (the GND/VCC/DI/CL pins) and 4 output slots on the other side. The other LED strip I bought just has 4 input pins. But neither of them will light up for whatever reason. I'm using a Sparkfun ESP8266 Thing Dev Board and an Anker battery to power my board. I've used the example strandtest code to light up the LEDs (the code in Arduino) and the code that I made that i'm using for my project. I've yet to see them light up. I still don't know whats wrong. I have GND connected to GND on the board, VCC connected to 5V (And I know these work because the battery powers up my board), DI connected to pin 13 on the Sparkfun ESP8266 Thing Dev Board and Clock connected to pin 2. I'll post pictures below (or the 2nd LED strip I bought) but ive tried using different pins for DI and Clock. Still no dice. Any solutions/suggestions. Thanks in advance

Answer 1

I had looked at the datasheet from adafruit website.

It says that there are Vcc Gnd CLK_in CLK_out SDO(Data Output) SDI(Data Input) pins

You can control the brightness of the LED using PWM.

But you should have a clock pulse.

Since the information provided in your question is very little to answer, I shall provide you with the common techniques people use for debugging an electronic circuit.

Use a multimeter and check for the voltage level of the Vcc Gnd in the board. Then check the continuity of the wires. After that connect the CLK pin to a DSO and check the SDI is high on the positive rising edge of the clock.

These tips will be able to find out the issue is.

If you can provide me with code and further details I would be able to help you definitely.
