16 Leds controlled by Potentiometer with two 74HC595 and ATMEGA328p AVR code

Instead of having the shift register count up continuously, I need to build a "bar graph" to visualize the value of an ADC pin. Start by adding a potentiometer to your breadboard, wiring it into one of the ADC pins. Using the format of the ledArray module as a guide, create \adc.h" and \[login to view URL]" files, and provide appropriate function(s) for getting an ADC reading. Hint: you'll need a function that performs an ADC conversion and returns the result. Call into this ADC module from your sketch to get a current ADC reading, and visualize this by writing appropriate values to the ledArray module. Do this continuously at a reasonable sample period (say, 50ms). Note that bar graph should be lled | i.e., all LEDs up to the appropriate mark should be illuminated.
