Hi i am new to arduino , i used a DUE to generate this waveforms , when ever i compile this code i get an error - "t_sample not declared" , then i defined it as a constant , then i got the output but the frequency isnt changing . i have connected the circuit properly.Please help , and what to declare the t_sample value as...?

Google is your friend.
It's a shame that the (seemingly anonymous) author hasn't fixed the tut in 5 years.
Thank you BJ HENRY for your timely reply , it was very helpful. The solution worked..
