In this tutorial, I will show how to build a Simple Bird Game Using Arduino. It is a low cost execution of the Bird Game with minimum devices and simple programming.
Simple Bird Game Using Arduino
Bird game was started by Dong Nguyen. Even this game is based on 2D Graphics; it became most popular on both mobiles like Android and IOS phones. The objective of this game is easy, try to fly the bird, which is called “Flying Bird” between the hurdles without hitting them.
Due to its habitual nature, the maker of this game discontinued the game from App store but after some time a correct version is again launched on App Store.
The popularity of this game amongst people was at his highest peak. So in this lesson, I will take the concept of the game and execute a Bird Game using Arduino.
Concept of Bird Game Using Arduino
The main concept of the Bird Game using Arduino is very easy. I have repeated the bird with the symbol “0” and the hurdles with s string of the symbol “#”.
As a matter of fact, I have build two such strings with mismatched combinations of the symbol “#”, one for the upper row and the other for downward row.
The main purpose of the game is to successfully pass the “bird” through these “hurdles” by pressing the button.
Components Required
- Arduino
- LCD
- Push Button
Circuit Diagram
From the above picture, you can gain an idea of how to execute this project. You need to interface a 16*2 LCD display with Arduino and also add a push Button. Coming to the LCD display, attach its RS and E pins to Digital Input and Output Pins 8 and 7 of Arduino. The Data Pins D4 to D7 are attached to 6, 5, 4 and 3 Pins of Arduino. First Push Button is attached to pin 2 and the other push button is connected to RESET pin.
Working
After connected all the connections as per the circuit diagram, update the codes and give power to the circuit. The time you turn on the power supply, the game begins by showing “START GAME” on the LCD.
Once the game starts, the Bird can be adjust its position with the use of push button. If the bird is in the upper side, by pushing the button, you can move it to downward and so on.
If the bird touches any of the hurdles, you will miss and the game is over. So this is an easy version of the game, there are only a few hurdles and if you successfully overcome all those hurdles, you will won the game.

Conclusion
So in this tutorial, I have made a Bird Game using Arduino, with LCD display and also a push button. This does not copy the original game but gives you an idea on how to execute a simple and easy version on your own.
So this is all for today. See you guyz in this coming projects. Take care.
