>>>>NOTE<<<< Although this code shows "Rotary Angle Sensor," it also works for the slide potentiometer, temperature sensor, moisture sensor, and light sensor since they do not have their own blocks


Programming the LED bar and an analog sensor

Arduino Code

 #include <LED_Bar.h>
 LED_Bar mesLeds(3,2);
 void setup()
 void loop()
