Story

This project is a one minute timer I decided to do it because: there are almost never examples with lcd I2C and because he always thought about having a timer made by me

Este proyecto es un temporizador de un minuto lo decidí hacer porque: casi nunca hay ejemplos con lcd I2C y por que siempre he pensado en tener un temporizador hecho por mí

how to arm

1. armar el boton

el boton se conecta a pin 13 a 5v y a gnd
