💻 Arduino Code to Read Potentiometer Values

Arduino_Basic_Codes_Analog_Read_Potentiometer

🔍 Code Explanation

  • analogRead(potPin); reads the analog voltage (0–1023 range)

  • Serial.println(value); prints it to the Serial Monitor

  • delay(500); pauses for half a second between readings

This helps you see how rotating the knob changes the analog value.

🧠 What Can You Do with This?

The potentiometer is one of the most versatile components for input control. You can use it to:

  • 🎛️ Adjust LED brightness

  • 🔊 Create volume knobs

  • 🧭 Read analog sensor values (e.g., temperature, force)

  • 🤖 Control robot movements manually
