Small Chip, Big Performance
- They are powered by either a 3.3 or 5-volt power source.
- These devices are programmable, in the sense that individual pins can be configured as either digital inputs, analog inputs, digital outputs, or pulse with modulated PWM outputs.
- digital input is the equivalent of a switch. Apply a high voltage to turn the switch on, low, or ground, to turn it off.
- Digital output is equivalent to turning a light on or off, perhaps in response to the voltage on a digital in pin. Pulse width modulation is a way of simulating an analog out. It behaves much the same as a light dimmer.

Thursday Night Net
Breakfast At The BrunchBox
Though not an official club function, some members have been meeting for breakfast on Tuesday mornings for many years, and in a variety of locations. The numbers attending have grown from around seven when I first started to attend, to as high as thirty plus. Good and reasonably priced good food and priceless comradary make this a very special occasion.
