    Ahhh! That is why! Tried it with 2 AA and works great! Thanks Gordon!

    Hello!

    Cool, I have an original Espruino (Rev 11.3b). I tried save() in the terminal yes. I swear this wasn't working yesterday but I think the code is on the board because when I've plugged in the micro usb the lights came on automatically. However, when I plug in a battery (9v) nothing happens. I'll update to use neopixel, thanks! And will try the on-board LEDs too! Thanks!

    I'm using a string of LED lights and creating various 'modes' I wan't to change to when clicking button 1. All works fine, but when I attach a battery everything freezes. Then when I try and save, then reattach to power nothing happens.

    What I need is a way for the battery to be attached and functionality to remain. I'm looking at documentation but getting confused. I am a Noob with this! Thanks in advance!
