Joy Gamer
Handheld gaming machine, based on the Arduino Leonardo, equipped with joystick, SD card and more.
The Joy Gamer is a handheld, programmable, game machine. It comes with a joystick, and SD Card slot, and an accelerometer. Check them out in our
store
! The Joy Gamer is built on top of Arduino so you can program your own games and load them up using a micro USB cable. We 3D print enclosures and joystick knobs to make the JoyGamer more ergonomic, colorful, portable, and strong. It can run on rechargeable lithium batteries, USB power, or any 5V power source with hook-up wires.
We have made tons of projects with JoyGamer and we share all our code with you! For example, you can make dynamic picture frames, drawing tools, gesture-based games, and even a fully function USB keyboard or mouse (by using the USB capabilities of the Arduino Leonardo. What's even cooler is that the JoyGamer shows up to your computer like an Arduino Leonardo so you can run any Arduino code you like on the Joy Gamer.

LEO Gamer Demo
Check out a few of the programs the LEO Gamer can handle. Including Adafruits Graphics test code, a keyboard, pong, and more!
Joy Gamer Demo Code
Here is a little Arduino sketch to get started with the Joy Gamer. The main loop is just 6 lines of code which outputs the current readings from the accelerometer and joystick. In the setup function we also check for an SD card and if there is one we print out "SD GOOD" and otherwise print out SD Failed.
While simple this code shows some of the common design patterns for coding on the Joy Gamer. First notice that we declare both Adafruit_ST7735 and JoyGamer variables:
While simple this code shows some of the common design patterns for coding on the Joy Gamer. First notice that we declare both Adafruit_ST7735 and JoyGamer variables:
Adafruit_ST7735 tft = Adafruit_ST7735(SS, 9, 8);JoyGamer jg = JoyGamer(&tft);This allows us to directly access all of the functionality of the Adafruit graphics library for the ST7735 screen directly by calling functions on our tft variable. However, we also pass a pointer to this variable to the JoyGamer. Don't worry if you don't know what pointers are, but thats what we get when we put the ampersand before a variable. Since the JoyGamer knows about the tft LCD screen our library can also create graphics. So when you are writing code for the joy gamer you can use functions from the JoyGamer library and/or from the Adafruit graphics library. This is why we have to include all those libraries at the top of this file.

Display a Bitmap on the Joy Gamer Arduino Code
Here is Arduino Code to show a bitmap image on the Joy Gamer. Our library does almost all the work for you :) Just call the function:
jg.bmp_load_and_draw_image("sample.bmp");
Make sure you have the SD card inserted properly, and loaded with the bitmap file "sample.bmp". You can of course load whatever images you want. The images do have to be in bitmap format and at largest 128 by 160 pixels. We wrote a little program to convert images into the bmp format, you can download it below.

Great library from Adafruit for controlling this LCD Screen

Adafruit Graphics Library
The Adafruit GFX library. This is the wonderful work of adafruit we just host it here for convenience. We made the most minor modification of replacing the dash in the library folder with an underscore so this baby is ready for your Arduino library folder out of the box :) Check out the
GitHub page
for the latest.

I2C Arduino Library
Similar to the wire library but more flexible. You may wonder why we cannot use the standard Arduino Wire library, it is because the MMA8453Q uses a repeated start condition for the read operations and the default Wire library cannot handle those without modification.
