Easy way to fade the on-board LED?
I want to fade the on-board LED from off to full brightness (preferably in a color of choice). Is there an easy way to implement this?
I want to use a for loop, however I'm not sure how to do that with the HEX value formating for the LED (e.g. from 0x00000 to 0xffffff)
Thanks! I couldn't figure it out (quite new to python).. Ended up with this:
def rgb_to_hex(red, green, blue): """Return color as #rrggbb for the given color values.""" return '%02x%02x%02x' % (red, green, blue) for i in range(256): color = rgb_to_hex(i,i,i) pycom.rgbled(256-int(color,16)) time.sleep(0.005)
This just fades from white to off, removing the '256' fades from off to white.. Probably not the smoothest way to do it, but it works. :)
for this puropose you can use HLS color scheme and manipulate brightness
e.g. use this lib
