Hi,
I am writing a script that will act as some form of kitchen timer. I have no display so I am simply using 5 LED's. My thoughts are that one presses reset and holds a push button down and LED's will light up one per second. One lit LED represents 5 mins of timing. I would have though that this would work by now but apparently not. I am getting led 1 on and no change what so ever, until after 5 mins it flashes. Any help please??
/*
Button
Turns on and off a light emitting diode(LED) connected to digital
pin 13, when pressing a pushbutton attached to pin 7.
The circuit:
-
LED attached from pin 13 to ground
-
pushbutton attached to pin 2 from +5V
-
10K resistor attached to pin 2 from ground
-
Note: on most Arduinos there is already an LED on the board
attached to pin 13.
