Visualize ADC data on PC Screen using USART AVR Project using microcontroller

ADC (Analog to digital converter) is a commonly used peripheral. We use it everyday to interface with several analog sensors. Many times a nice visualization of ADC data is required during learning about new sensors. For example you just bought a analog sound sensor, and try to do some fast experiments that how it performs.
