I have square wave coming out of arduino and used RC filter to convert square wave to sine wave. But the sine wave out of the filter is shifted in amplitude with 2.5V center high peak at around 2.75V and low oeak at 2.25V as shown in the graph.
1) How to make the filter sine wave output amplitude starting low peak at 0V?
2) How to make the filter sine wave output with center at 0V? here capacitor should work, I tried but I didn't get the dc removed.
