Arduino Toolboxes : Analog Level Visualizer

Things used in this project

Hardware components

Arduino UNO

LCD 16x2 Shield

Software apps and online services

Arduino IDE

Story

In This Video I Have Created A Visual Representation Of Analog Values At The Same Time Is Very Good For A lot Of Purposes Specially When The Analog Values Needed At the Same Time for Understanding The Signal And Calibration On Several Sensors At The Same Time .. etc.

This Image Shows The Information That Is Displayed On The Screen And How It Can Be Useful And Easy All In View.

This Is One Of A Series Of Tools Aims To Enhance Working With Components And Sensors.
