The author repeatedly needed several different digital signals for testing his circuits, and a simple function generator did not provide a satisfactory solution. He quickly developed a design for a pulse generator with three outputs, as described here, which can generate a variety of pulse trains with adjustable frequency. The heart of the circuit is an ATtiny13.
