Arduino Lesson 3. help

by Glassy123 on Fri Apr 15, 2016 4:01 am

Hi all,

I'm having a weird issue with this lesson. I have everything connected as it should be, but when everything is connected I only get a pulse of green and light green, but with the ground unplugged I get a pulse of red/blue/purple. It looks like the green colour signal is not being sent with the ground in.

I'm using a seeeduino in combination with the standard parts, have tested with two different boards and same result.

Lesson is here: https://learn.adafruit.com/adafruit-ard ... leds/parts

A pic of the setup:

Any help would be greatly appreciated! Thank you!

Are you using a common cathode led or a common anode led?

Ah looks like I have an anode, thought it was a cathode this whole time...silly me!

Finally got it to work once I changed the code around

Thank you!
