i want to make countdown clock with adjustable time and control some relays
and i want to use 2 displays seven segment and lcd 20*2

lcd is working fine but seven segment is flickering.

Code: Select all

#include <LiquidCrystal.h>
#include <Bounce2.h>
#include "SevSeg.h"

#define LED_PIN       13

#define BUTTON_PINin  22
#define BUTTON_PINp   10
#define BUTTON_PINn   11
#define BUTTON_PINr   12
#define BUTTON_PINf   27
#define BUTTON_PINb   26
#define BUTTON_PIN60  25
