Arduino Endless Run Game Using LCD Display & Push Button

Featured Image.png

Hello friends welcome back to "Techno-E-solution," In this tutorial we are going to build a simple "Arduino Endless Run Game Using LCD Display & Push Button." This is very simple & DIY game which we are going to make in this project we use LCD I2C module to reduce circuitary. so this is our first game using arduino, so let's make it.
