Digispark - Is the internal pull up resistor good enough for a switch?
Digispark - Is the internal pull up resistor good enough for a switch?
The digispark is a very small arduino compatible microcontrller: http://digistump.com/products/1 It's got I/O pins, and they have pull up resistors, though it seems they have a smaller value than on a full arduino. I'd like to sense a switch closure with the Digispark, and I'm not sure if I need another resistor or not. My EE skills are still ...
