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.

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.

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

Ok, still search for DAC!

"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 a motor's no-load current at a given voltage is much less than it's resistance would suggest? Learn more...
