Hello folks !
I would like to ask you for some help with my first Arduino project because I'm a noob.

I will place a magnetic sensor on a frame and a magnet on a wheel.
I need to make a counter with that, which will display the number of turn the wheel does.

To put you in context; it's for some old ladies, they need to roll their wool things and have the same lenght of wool wire or whatever you call it, for their looms.

What I have so far:
- Arduino UNO

What I think I need:
- A LED display
- A display sheild ?
- Some CODE hehe

I really hope I could get some help on this forum and thank you well in advance

To sum: Magnetic sensor send a pulse, and those pulse increments on a display, with a reset button  :smiley-red:

How many turns?  If that's not greater than 99 then you could use a 2 digit, 7-segment LED display.
I you get an LCD then you can display a very large number.

Hey thanks for your reply
I will need 3 digits

This would be perfect:

Well, that LCD Keypad shield plugs right into the Arduino, no loose boards, and it's more functional.
(The LED board is designed around a 328P... hmmm, I've heard of those somewhere...)
