Currently, i am doing electronics kits. However, the result is not coming with my expected results. The counters will start at 999 once battery is connected. Reset function is good condition which can reset the counters to 0. Come to the 'UP' and 'DOWN', the counters will immediately jump to number 6 instead of 1 then followed by 10. it is constantly for further button pressed as 16,20,26,30.... While, down counters will jump here and there , sometimes reduce 1, 2 , 4 or 7. I hope that some1 can help me since it is good when stimulating with proteus. The counters can increase1 by 1 and decrease 1 by 1.
