[120] Flipper-Zero: Introduction to Analog Sensors
The Flipper Zero has 6 GPIO pins that can read analog sensors! These pins require the voltage to be 0-2 volts (or 2.5 volts with custom configuration) and recommend a total resistance of 10K ohms or less. Learn how to convert analog resistance and voltage sensors to levels that are compatible with the Flipper Zero!
Future videos in this "ADC" (Analog to Digital Conversion) series will cover writing your own Flipper applications to communicate with these sensors.
