Programming and Result: ACD (Analog to Digital Converter) Using Interrupts

The ADC (Analog to Digital Converter) converts an analog voltage between a range of voltages and provides an 8 to 10 bit number in proportion to the voltage sensed by the ADC. In this video, the ADC automatically notifies of it's conversion complete using an interrupt. A potentiometer is used as a voltage divider to provide variable voltages to the ADC pin.

The LCD is used in this example to show the converted output from the ADC in a number from 0 to 255 (8-bit). #include #include #include "MrLCD.h" int main(void) { InitializeMrLCD(); //Configure the ADC ADCSRA |= 1 <
