/* Arduino Snake for VGA monitor - by Roberto Melzi. Version 1.1 - October the 10th, 2015 with sound Arduino IDE 1.6.4 Version 1.4 (December the 13th, 2016) snake array in byte, more memory for variables available, allowing lenght increment of 5 pixels instead of 3. Version 1.5 (November the 12th, 2017) other variables in byte, score up to 10, adding vgaPrint() and vgaPrintNumber, */ #include #include #define FNT_NANOFONT_HEIGHT 6 #define FNT_NANOFONT_SYMBOLS_COUNT 95 #include #define BUTTON_1 12 //digital #define BUTTON_2 11 //digital #define BUTTON_3 10 //digital #define BUTTON_4 13 //digital // NB: pin A0 is used for the audio!
