Hello,
I'm designing a simple object counter whereby it will be installed at a box. The main purpose is to count the number of object being throw into the box. I'm using arduino Uno as microcontroller, IR sensor to sense for object and 4 x 7 segment LED to display my number of count and a push button to reset the number of count.
Pins as allocated,
IR sensor = A0
Button = 6
pinA = 13;
pinB = 11;
pinC = 5;
pinD = 7;
pinE = 8;
pinF = 12;
pinG = 4;
digit1 = 9;
digit2 = 10;
digit3 = 3;
digit4 = 2;
I've no problem in displaying 0-9 count. I'm facing issues to display 2 digit. I've tight budget and i hope someone could help me.
