Hello my name is Anthony and I'm 14 years. I want to share my Code for arduino lcd loading bar
Feel free to use the code and tell me what you think

#include <LiquidCrystal.h>

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

byte percentage_1[8] = { B10000, B10000, B10000, B10000, B10000, B10000, B10000, B10000 };

I have trie to implement your code but I'm not a good programmers can you help me ? In the german forum helps me to create a simple code that light up and down a LED in a light sequenz and now I would like to make a simple progress bar for the time who need the LED Sequenz can someone help me please? Thank you !!!
