Understanding voltage dividers means understanding Ohm’s Law. A common use for a voltage divider in most projects is to monitor a battery. Say you are powering your circuit with a 9V or 12V battery. Microcontroller boards don’t do well with those voltages.

In a future video, we’ll come back and look at more circuits that can use voltage dividers.

Episode Notes

Correction: There is a mistake around 3:00. I say “91 millivolts” and I should have said “910 millivolts!”
