I have a have project of Up Down counter using arduino with seven segment.In which when i continuously pressed the push button , the counter moves upward from 0 to 99.And when i release the push button counter moves downwards from the previous values For example: i continuously pressed the button counter moves 0 to 58 then at this instant when i release the button , the counter moves backward from 58 to 0
The problem is that when i simulate the code in proteus software , counter starts from 99 because button is not pressed . but when i pressed the button counter moves upward not accurately also the other big issue is that when button again released , the counter does not moves backwards although counter moves upwards continuously and button is not working (if button is pressed or not) may be counter engage in while or not or may be else here my code and proteus simulator cicuit image
int num_array_1[10][7] = { { 1,1,1,1,1,1,0 }, // 0
{ 0,1,1,0,0,0,0 }, // 1

{ 1,1,1,1,0,0,1 }, // 3

If button pressed ----------> logic goes HIGH If button release ----------> logic goes LOW
please resolve my problem i have tried 2 weeks for solving this problem but still in stuck Any little advice will be important for me
