Hi there, I have the following code: int i = 0; void setup() { Serial.begin(9600); } void loop() { if(i == -1){ Serial.println(i); } i++; } When I uploaded this code to my Arduino Uno, the Serial monitor started printing out "-1". Am I crazy, or is this program defying the laws of …

loop runs very fast. It only has to execute around 65536 times to hit -1 (an int will overflow to the maximum negative value). Eventually you hit -1 and it gets printed.

HELP! if(variable == -1) causing variable to = -1

I just have to say, I love how fast this forum responded!
Other forums... well, you probably know how long it can take to get answers on other forums.

New(?) funky forum feature?
