UKHeliBob:
My question: Why do you need to reset the Arduino ?
To upload new sketches to the arduino (wirelessly).
Grumpy_Mike:
Yes
What measures would you recommend?
[Edit] Some one told me to just throw a resistor in there. Okay but it's still 5 volts, right? Would this be 'good enough'. Or should I use a transistor? I'm looking for the correct way to do it.
