Voltage divider output exceeds 5V or is below 0V. Fix: Recalculate resistor values. Ensure common ground between sensor and microcontroller.
Numerous educational websites (Microcontrollers Lab, Engineers Garage). Features: voltage sensor proteus library
If you just need to measure or detect voltage without a specific module, you can use built-in tools: Voltage divider output exceeds 5V or is below 0V
