Have a 230V to 11V transformer. Want to run it to have a spark gap. First thought creating an Sine Wave would be easy with arduino but apparently not that easy. Idea is quite simple but the value I monitor fluctuates around 280 rather than going all the way up to 255 and then falling to 0 in a loo…

AC for running the transformer

for(i;i<256;i++)

How about initializing "i"?

Analogue out 9 != analogue in 9
