How to turn OFF the lights.

Welcome to the ht1621-7-seg wiki!

If you, like me, want to turn off the lights of the LCD display with the ht1621 controller and you justa can´t via Code you just need to make a little trick with the board of the display module.

Listen. In the backpart of module exist a little piece of tin solder, you just need to remove it. And the lights are gonna turn OFF, but you can't turn on the lights again because you disconnect the led, so, if you need to control the lights via code, you need to put a little piece of tin solder in a place next to the tin solder that was removed, and thats the solution.
