Arduino Simulator Example - "LED bar graph" 📊

Arduino "LED Bar graph" on Arduino simulator

 Summary

Arduino "LED bar graph" The bar graph - a series of LEDs in a line, such as you see on an audio display - is a common hardware display for analog sensors. It's made up of a series of LEDs in a row, an analog input like a potentiometer.

Wokwi Arduino simulator is used here as it is free and easy to use online. 

Tip✅: Always connect a resistor of about 220 ohms in series with the LED. Do not connect them directly to the Arduino Pin.
