Hi, i'm trying to build a two timer astable oscillator with variable dutycycle and fixed frequency.
I built the circuit attached but i get nothing on my oscilloscope.
I didnt copy this circuit entirely i have a cicuit with 1 timer that has variable duty cycle and fixed frequency, and i have a circuit of a 2 timer astable oscillator and have tried to merge the 2 together.
I expect i have made a design mistake, could anyone help please?
