I need a way to modify this circuit so that the Duty Cycle can be changed with an input DC voltage of 19mV to 25mV.
The input will be from a K-Type thermocouple and %5 duty cycle will need to correlate to 19mV with 95% being had by 25mV in.
I found this online, and even if I can't make the input work, I can still use this as a manual controller. I just wanted to present it and find out if it can be done.
My skills are fairly limited. I can build this easily, which played a part in choosing it for my basis.
Thank you for any ideas.
