It is about pong on a MAX7219 matrix but i have some trouble figuring out the shematcs on where to place the buttons /* * Play pong on an 8x8 matrix - project from itopen.it */ #include "LedControl.h" #include "Timer.h" #define POTPIN A5 // Potentiometer #define PADSIZE 3 #define BALL_DEL…

Hi, [image] kenny_newbie: const uint8_t LEFT_SWITCH = 8; // bat move right switch pin const uint8_t RIGHT_SWITCH = 6; // bat move right switch pin These two lines tell you D6 and D8. You will need to connect you buttons/switches between; D6 and gnd. D8 and gnd. Tom... :grinning: :+1…

Looks like the only input is one potentiometer on POTPIN.

It looks like the LedControl library is being told to use pins 10, 11, and 12. Find documentation for that library to see what those three pins connect to on the 8x8 LED array.

im sorry, i understand my mistake; i was actually trying to understand whee to place the buttons according to the code

The code, as presented, doesn't use any buttons.

im really sorry - i thought i gave the right code ended up pasting another code // Use the MD_MAX72XX library to play Pong // // Play pong on just one matrix. Bat is controlled by 2 // switches for left and right movement. Optionally use // a pot on analog input to set the speed. // #include <MD_…

this is the part where the buttons come in - what pins do the buttons correspond to ? // -------------------- // Mode switch parameters // const uint8_t LEFT_SWITCH = 8; // bat move right switch pin const uint8_t RIGHT_SWITCH = 6; // bat move right switch pin #if SPEED_FROM_ANALOG const uint8…

Newbie here- can somebody help me with explaining the code here and the shematics
