Arduino LCD Basic Game

Ye my name is Simao and I gonna explain you how to make the most basilical LCD game for Arduino.I don't no who create this game because it's like a classic right now.The game consists on a little stick man that is runing there are a random bars that appears ,when one of the bars are near the stick man it needs to jump,for that we press one push button to jump and start the game,if the stick man colides on a bar the game stops and you read your points,the game ends when you colide on something.

1. Arduino board (you can use MEGA,UNO,Pro Mini,NANO,DUE,Duemilanove,UNO WI-FI...)
2. BreadBoard.
3. Some Jumper wires
4. 16*2 LCD display
5. PushButton

Conect the wires like the schematic .

Put this code on yourArduino IDE and upload.
