...ESP32 and MPU6050. (With guidance I can use any other preferred sensor instead). Initially powered by USB, there is a battery connector on the ESP. Sensor firmware programming was done via VS Code, so I have gained a bit of practice using that. The desktop application attempt was I think done in some version of C and using Qt. Previous attempts "might" have been in Python, and I do not know what might be better for the shorter and/or longer terms of project development and expansion. I should hopefully have all the code developed by the previous contractor for reference, as well as select exhibits from other previous contractor attempts that might be helpful. I can consider project or hourly quotes/estimates. I could have inadvertently missed any number o...

I require a simple solution (most likely by using flip-flops) for the circuit that will take digital signal of fixed frequency and variable pulse width and then alternately toggle two output pins. However, both output pins states should go to 0 when the input signal goes to 0. Take a look at the attached timing diagram as the task is immediately understandable. Please note that only CD4xxx (4000-series) parts can be used in the design.
