## Controlling the backlight
It's a bit counterintuitive but according to [Notro's wiki](https://github.com/notro/fbtft/wiki/Backlight) you can control the backlight like this (tested, works!):
Write a "1" to turn it **off**
echo 1 | sudo tee /sys/class/backlight/fb_ili9341/bl_power
and a "0" to turn it **on**
echo 0 | sudo tee /sys/class/backlight/fb_ili9341/bl_power
