G+_Bill (CryptoMoore) Posted January 29, 2016 Share Posted January 29, 2016 Messing around with a Arduino pro micro and trying to just do a simple led blink using the code from KH173 "BasicWS2818" and cannot seem to figure out why lights not working. See pic but the following is the pins: Data pin=5 Gnd=ground Vcc=power 5v When I connect just get a quick blink in the lights.... Any thoughts. Thanks in advance. Fr.

G+_Ben Reese Posted January 29, 2016 Share Posted January 29, 2016 Are TX0 and RX1 supposed to be soldered together? Link to comment Share on other sites More sharing options...
G+_Ben Reese Posted January 29, 2016 Share Posted January 29, 2016 Just took a look at the code in the show notes too. It has the DATA_PIN as 7. Did you update that in your code to 5? Link to comment Share on other sites More sharing options...
G+_Bill (CryptoMoore) Posted January 29, 2016 Author Share Posted January 29, 2016 Ben Reese yes I changed to 5 on your other ? Tx0 and RX1 soldered... not sure..I could try to bridge them on the breadboard... not sure if I will get magic smoke Link to comment Share on other sites More sharing options...
G+_Bill (CryptoMoore) Posted January 29, 2016 Author Share Posted January 29, 2016 Ben Reese ahh I see what you mean did not catch that -- they were bridged.. i fixed and still have the same issue.. no lights but I am getting the sonar data back and that appears to be working.

G+_Bill (CryptoMoore) Posted January 29, 2016 Author Share Posted January 29, 2016 I am also getting an warning on the FastLED library by not sure it is an error..

G+_Scott W Posted January 30, 2016 Share Posted January 30, 2016 Is your pro micro a 3.3 or 5v model? If its a 3.3v you will only have 3.3v on the Vcc pin, the RAW pin will have a little less than 5v if powered with the USB cable. If it is a 3.3, move the LED power the the RAW pin and try it.

G+_Scott W Posted January 30, 2016 Share Posted January 30, 2016 you should also un bridge the txo and rx1 pins as mentioned Link to comment Share on other sites More sharing options...
