Algorithm:
Explonations: Firstly program will generate random number and will turn on LED, next, what will do this program is checking in the loop which button was pressed. Then move users LED to the correct side and compare: are random LED is on the same position with user LED, if yes - generate new random number and change LED.
Sketch:
// Leds for user
#define LEDU1 8 //Left one
#define LEDU2 7
