Got a request for the code that goes with post #334, (Using a LED and switch on the same I/O pin). Forgot to add it to that post so here it is now: /*   Demonstration how to use a pin as an output to a LED   and at the same time, as an input from a switch.   Note:   The LED(s) 'must' be connected to +5V (CA) through a series resistor.   The switch is connected to GND through a 240 ohm resistor.   Typical setup for SMD LEDs:   +5V White  LED - 4.7K - I/O PIN - 240R - Switch - GND   …
