With push buttons, you will be able to choose a waveform shape (sine, triangular, sawtooth, or square) on both DAC channels and change the frequency of the generated signal. Sine waves appear in nature all the time (ocean waves, audio waves, radio waves, pendulum motion), and because they vary smoothly over time (and are easy to make, as we'll see below), we'll borrow them to make our LED vary smoothly between on and off. Resistor R1 is used to limit power. Components List3x - 2200 uf 35v (electrolytic capacitor)13x - SR3100 1x - arduino nano/uno/mega6x - cemramic 10uf 16v or above8x - 10k ohms 1/4 watts8 x - 4.
