this is a Robot Heart Simulation Circuit. We are using 2N6027, the PUT - Programmable Unijunction Transistor type. Its symbol is very different from a bipolar transistor. Imagine we could control the heart of the robot automatically via digital potentiometer, for example, MCP4231, a Digital SPI Potentiometer ([ Ссылка ]).
