An analog input signal is applied to an 8-bit resolution analog-to-digital converter (ADC) that is sampling at a known rate. The output bits are displayed on LEDs. The data is also immediately applied to a digital-to-analog converter (DAC) at the same sample rate.

All of the features are implemented using an ATtiny1616 and its internal peripherals.
