hello.
i have a school project and i need to make a counter using 6 buttons and a 2 digit segmented display to make a counter that counts up to 99 and i couldnt find any examples to make a counter with 6 push buttons, button one counts with +1 button two +2 button three +3 and so on to +6 can someone help me with the code and the arduino build
thx
Welcome to the forum
Your topic was MOVED to its current forum category which is more appropriate than the original as it has nothing to do with Installation and Troubleshooting of the IDE
Can you find an example that add 1 to the display when a button is pressed ?
yes i can i have an example
In the Arduino IDE, use Ctrl T or CMD T to format your code then copy the complete sketch.
Use the </> icon from the ‘reply menu’ to attach the copied sketch.
Always show us a good schematic of your proposed circuit.
Show us a good image of your ‘actual’ wiring.
Give links to components.

The clumsy way to do what you want with 6 buttons would be to repeat the button reading and number setting code 6 times but have it add a different number depending on which button is pressed
Try it starting with 2 buttons
NOTE : there is a much better way to do this
can you explain the better way please?
Use an array to hold the button pin numbers. Iterate through the array and read the pins. If you find a button pressed then use the current array index to determine what to add to the count
but the problem is that i dont have pins left so only 1 and 2 and a couple analog pins
Were you keeping that a secret ?
You can read and differentiate between multiple different button presses using a single analogue pin
Multiple button inputs using Arduino analog pin « RAYSHOBBY.NET.
as an example
i tried and it didnt work isnt there a example availibe whereby i can add buttons ?
Post the sketch that you tried and a schematic of your circuit. A picture of a hand drawn circuit is good enough
What exactly doe "didn't work" mean ?
You can also use a Arduino Mega or a shift register to increase the number of inputs as well.
