If you attach a bluetooth module you can wirelessly program from an app like BlueTerm. Theres also an app called Android script that lets you program the espruino with OTG(USB micro to female), Dave Smart made a video on it here https://www.youtube.com/watch?v=_Nwq5Quhg4s

How many Amps does a 50 led strip of ws2811s use when all leds are set to white?
I've got some old psp chargers/supplys that are 5v at 2 Amps.

Huh, just tried my other module and it worked, so it was most likely the wiring. But i'm sure i checked that yesterday. Thanks Gordon you're always so quick to reply.

EDIT: both modules work

Same happens to me. When i powerup the Espruino the matrix takes a second or so to startup, then every led turns on. Nothing happens after that, not even disp.off()

Aww, Does that you cant use the HC-05 as a master at all as you cant scan for slaves? Its purely a slave.

I just tried out the Nunchuck it's very easy to use, but i wanted to use a controller to controller to scan for an RC car. This has been done on the Arduino but i think they used a usb bluetooth shield

I would like to use a Wii or Dualshock 3 game controller to control an RC car. However i have no idea about how to do this. Is there a way to set the HC-05 to Master and scan for the game controller?

I'm sure this would be pretty simple with the use of eval, but i don't have my cc3000 module yet so i cant test :( Never the less I've got plenty to do with this awesome Espruino.

Personally i learned JavaScript for the web and for Unity game design. What about you?
