Hello friends welcome back to “Techno-E-solution” in this article I’ll show you how to make “Flappy bird game using arduino Uno & LCD display”. This is beginners level project, if board at home & if you want fun with arduino let’s make this game. This game is very simple to make here we use Arduino Uno & LCD display also used a Push button to play the game, So let’s make it….
