As the title states, will having a killswitch on my arduino, damage it if used too many times.
WHat i mean is this,
im building a soccer robot for a competition and it is very lengthy in the program to have it check the position of the switch inside the program, so i had an idea to incorportate a kill switch in the small circuit that supplys power to the battery, it would be an spst switch, which would just remove all power going to the arduino, effectively turning it off when i dont want it to turn on.
In a standard soccer match a kill switch will be hit roughly 20 times in 10 minutes, will this damage my arduino, or am i ok to do it like that.
I don't believe there is any limit as to how often you can cycle power to the arduino.
Wouldn't it bog things down a lot having the arduino restart every 30 seconds?

Shouldn't be a problem at all, as long as the kill switch removes power to both the arduino and everything wired to it. You can have problems if you power off an arduino board but still have live input signals from other external components or modules that might remain powered up.
I believe that electricity can "bleed through" the processor if you disconnect VCC with voltage applied to a pin. At least that's what I've observed.
If it is possible for a pin to be powered while the processor is not powered I suggest that you apply the kill-switch to RESET. Simply connect the RESET pin to GND when you want the robot to stop.
