🔗 *The full guide* : _https://core-electronics.com.au/guides/analogue-electronics/getting-started-with-voltage-dividers-a-practical-guide-for-makers/_
In this guide, we are going to learn about *Voltage dividers* in a practical and approachable sense for *makers*. We will be working through an example of *monitoring* a LiPo *battery voltage* with a *microcontroller*, and we will work through the Voltage divider diagram and *equation*, as well as simulating it in *Falstad* - a *math-free* way of calculating the needed *resistors*. We will also go through wiring up the divider, as well as some *helpful code* for our Pico microcontroller to read the input voltage of the divider.
