JoyGamer Bitmap Slideshow Arduino Code

This code expects a bunch of bitmap files in the root directory of an SD card named exp0.bmp, exp1.bmp, up to exp[num_pics].bmp. You can create these files using our bitmap converter tool . In the main loop a random number between 0 and num_pics is chosen then we construct the filename correponding to this image in the line: 
 pic_name = base_name + cur_pic + String(".bmp");
We display that image wait 3 seconds and do it again. All the necessary libraries can be downloaded from our main Joy Gamer Tutorial .
