This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino ... It is a combination of 8 LEDs (the decimal point -DP- is the ...

Leaving the joke aside, let me show how you can achieve this. You will need the Arduino Board, a 560Ω resistor, and LED and the code example below. We set the pinButton variable as integer 8 and we ...
