Nextion build an HMI with PWM I/O
Budget: $30 – $250 CAD
This project will need to have user input a desired frequency (1-1000hz) and the nextion will be using the expansion card making two output generate the signal as follow:
user ask for 1 hz
Nextion will generate :
1hz 50% duty cycle on first output
1hz 25% duty cycle on second output
there will be a small menu that will need to be created see attached file.
This will be only the initial phase of this project, if all goes well, there will be more phase to finish the HMI and add make user HMI more convenient.
