Hi all,
In another post I mentioned this had been covered here... but I couldn't find anything.
Any reason this would not work:
Connect power to the Picaxe power pin through a momentary action push button, perhaps with a capacitor/resistor to ground. This will power up the picaxe when pressed and held.
Raise a pixaxe output pin, at power-up, activate a FET/darlington/low power relay to connect power to the picaxe power pin in parallel to the push button. This will maintain power when the push button is released.
In software, lower the output pin to power down when required.
Seems simple - any reasons this wouldn't work?
Thanks
