Hi All.
What i wanted from the above circuit was a 0-5 volt , low frequency (LFO) generator that could be used as a variable analog input to an Arduino to vary the rate of PWM.
Attached is a circuit that was on You Tube.
It seemed to tick all the boxes.
It didn't------heard that before ?
The triangle side was good , although the output was low according to the authors 1.4volt----only 750mv.
I used a variable pot for R1 and that provided the desired frequency range
When it came to the amp , things went pair shaped.
Very distorted wave shape and only about 2 volts P-P , author claimed 5 volts P-P.
Any thoughts
Best regards
