This video explains how you can estimate the flight time of your quadcopter by measuring the voltage of your battery. You will learn how to calculate and build a voltage divider allowing your Teensy to measure voltages up to 16 Volts.

The purpose of this video series is to learn the basics behind a quadcopter drone and enable you to build one yourself, by dividing this challenging project in several easytounderstand parts. You use the capable Teensy 4.0 microcontroller together with the easytouse Arduino language.
