An easy way to debounce your input is to use a short delay - twenty milliseconds would be enough. Put it in the body of the if that executes if the state of the button has changed. Generally, using delay is frowned upon because it tends to make your pr...

Non ho cambiato niente perché in 10 minuti non ho neanche chiuso l'ide, ma solo attaccato Arduino da un'altra parte. Comunque ho ricontrollato ed è tutto ok.

Je ne sais pas s'il y a encore une console facilement accessible sous seven, je n'utilise plus Windows depuis un bon moment.
S'il y en a une, il serait intéressant de lancer l'IDE dans une console afin de voir si Java retourne des messages d'erreur.

I should, perhaps, admit that chars and strings in C confuse me somewhat, but does charArr[0] = char(myArr[0]) do what you want ?

Liter per time: 24.8400
...and that is not what I had expected.
The engines I develop this flow meter to, uses between 3 and 50 liters per hour.

24 is between 3 and 50, so ?? Be aware that this is the consumption per hour!

My light–up TARDIS pin uses a color-changing LED, an SMT LED (behind the POLICE BOX sign), conductive thread, and a sewable battery holder- all from Adafruit Industries.

I also followed the "LED sequins" tutorial to prep the SMT LED for sewing.

I've been working on this little project on and off for several weeks, and I'm so happy it's finished! On the surface it's just a TARDIS badge made of wool felt, like others I've made before. But underneath there are LEDs, a battery, and a conductive thread circuit. When the battery holder is snapped shut on the back of the pin, the pin lights up: the lantern on top, the "POLICE public call BOX" sign, and the windows. The windows are lit by an LED that changes color every few seconds (I like to imagine the time rotor is going crazy in there, even if one usually can't see anything through the windows).

This project took a long time mostly because I had to gather a lot of new materials, including ink-jet printable plastic film, very thick felt (I cut up some coasters I found at Target!), and high-quality iron-on transfers- not to mention the LEDs, sewable battery holders, and conductive thread!
