Hi I bought a strip of WS2812B but I'm having trouble following any of the tutorials for LED light strips.
The problem I have is that when connected to the original espruino board when i run the sample code from http://www.espruino.com/Individually+Addressable+LEDs , only the first LED on the strip lights up and the colour does not seem to be relevant to what is specified in the program.
I saw this thread but i'm not sure if it's relevant and has gone over my head anyway :/

Hi I tried to see if i could find the where to edit this page in one of the repos but both pinned and unpinned boards are available from makersify. I found this because i believe the other stores were out of stock of pinned in the UK.

Yes that's great help thanks! My only question now is about how the square wave on A5 can be between 0 and -3.3V when A6 is 0. Is this a good answer http://electronics.stackexchange.com/questions/10322/what-is-negative-voltage ?

@Ollie not to worry! I hadn't had a chance to try again since my post. Although I have gone out and bought a normal IR LED since to try out incase I still have problems. So i'll have a try again tonight and post back how it goes.
@Gordon Thanks for the clarification. So I take it that IR LED is constantly shining the 38kHz frequency and the digitalPulse through the other pin is interrupting that at the scheduled times in order to actually transmit the signal?
If that's the case I was reading that diodes
In electronics, a diode is a two-terminal electronic component that conducts primarily in one direction;
Does that not mean the the 38kHz turning on and off is very weak?
Here are some other pictures from the documentation for the module incase you are interested. One shows it wired to output, ground and power of an Arduino :$

Would I be right in assuming the analogWrite should be effecting the power pin on the module I pictured?
// Start the 38kHz square wave analogWrite(A5,0.9,{freq:38000}); // Send the pulses digitalPulse(A6, 1, times); // Wait until pulsing is finished -
Hi I've been trying to follow along with http://www.espruino.com/Pico+Infrared but I am having trouble with emitting IR from the LED. I purchased a starter pack intended for an UNO and the IR led is attached to the PCB. I've been trying to figure out how it should be connected to the Espruino because one of the pins is a ground I'm not sure that it can be written to with analog write ?
Any help would be greatly appreciated, really enjoying Espruino so far :D
p.s. using a full size espruino
I found the issue an i'm feeling very foolish right now! The led's came wrapped up the wrong way round and I assumed plugging into either side would work. But then I saw there was an arrow on the actual strip and I had the lights plugged in the wrong way round!
