In this introduction to AVR microcontroller ADC modes, learn the benefits free running adc, auto-triggering adc, and single conversion adc. Single conversion adc is the most basic mode, and is good for applications where timing Is less important. Free running mode is important when you want to get the most samples from the adc possible, and is the fastest ADC mode. Auto-triggering mode allows a second peripheral to control the ADC conversion timing. Check out the example project below!
