Will I be able to program the Nerdkit microchip to randomly choose different voltages. |

"Will I be able to program the Nerdkit microchip to randomly choose different voltages." From what? A little more detail might help us answer. Ralph |

When I have a 9 volt battery connected to the microchip, can I program the chip to randomly choose different voltages for an output? |

You will be sorry if you have 9volts connected to the microchip. That is what the voltage regulator is for, to reduce the voltage down to the allowable 5 volts. Search the forum for DAC as in Digital to Analog Converter there are a lot of discussions about DAC one of them should adress your question. Ralph |

Okay, 5 volts. Can I still do the random voltage between 0 and 5 volts? |

Ok, still search for DAC! Ralph |

"Can you" Sure. "how would I" is more difficult. I would suggest using a voltage divider or some series resistors to step down from 5v or a MOSFET/Relay to control more than 5v (i.e. 9v, 12v, 24v, etc.) Each pin could yield a different VOut while the MCU is kept in the dark about the specifics. Pseudo Randomness is something, I believe, the MCU can handle for you. |

Did you know that the printf format string "%.3f" will show three digits after the decimal point? Learn more...
