Simplest ever digital / analog neuron: "SEDAN-6"

The author continues with his series on artificial neuron construction. Using the smallest commercially available microcontroller, a 6-pin 8-bit unit, he has created several types of McCulloch-Pitts neurons and logic elements suitable for inclusion into various kinds of artificial neural networks. Additionally, by employing the on-chip analog comparator and simple off-chip stratagems, he has also implemented Hebb neurons and his android emotion emulator. These designs constitute the simplest artificial neurons which can be embodied using a microcontroller, and which are suitable for a wide variety of applications.
