Speedcubing timer on Arduino

I'm trying to get my program work. I'm making speedcubing timer, but I found code only for OLED and capacitive buttons. I want to use I2C 16x2 LCD and normal buttons.

It will work as shown here: https://youtu.be/b-o7CAp13tc?t=64 at startup, timer is ready. If you place TWO Hands on buttons, you must hold them by 2-3 seconds. after waiting that 2 seconds you can solve the cube. After solving you must place two hands on buttons again and stopwatch will stop.

Can anyone modify my code to get it work? Here's my code:

#define OLED_RESET 4
Adafruit_SSD1306 display(OLED_RESET);
#define Red 7
#define Green 8
#define ResetB 6
#define Sensitive 20
#define delayRun 2000
#define blinkDelay 75
#if (SSD1306_LCDHEIGHT != 64)
#error("Height incorrect, please fix Adafruit_SSD1306.h!");
#endif
