FastLED not working on WS2812b LED strip (using teensy 3.6)

Hello everyone!
I would really appreciate if someone could help me with this.
I have bought a teensy 3.6 to drive my ws2812b LED strip, however when i used a simple blinking code on github using FastLED
https://github.com/FastLED/FastLED/blob/master/examples/Blink/Blink.ino
My Led strip remained turned off.
Can anyone please let me know what am doing wrong?
I have connected the LED strip data pin to pin11 on my teensy and then wired the ground of my teensy to the ground of the power source.
Any help is appreciated !
 
A photo of your setup might be needed here.

Things to do:
Check that there actually is power on the start of the strip
load up blink, change it to toggle pin 11 and change the timing to about 5 seconds and confirm the Din pin toggles with a multimeter
load up the neopixel library, set it for say 10 pixels and try it on pin 11 as well.
If all of that works increase the pixel numbers and see if your power supply is up to the job of driving the whole strand

It does not sound like you have a level converter, so problem may be trying to use 3.3V logic on 5V strips, but that generally manifests as erratic operation rather than none at all
 
Thank you for your reply! I will take a photo of my setup when i can. I’ll get back to you when i have used the blink example.

Also am using an external adapter to supply 5v and 1A for my strip!
