Visual programming has been mainly used in education side. When it comes to complex hardware design, it is not very useful. Although currentlty we ONLY enable the GPIO read write. We enabled a popcorn robot with sound positioning and voice recognition.

See how powerful wikit would be with flowchart programming!

additional electronics device list

microphone x 2

resistor

transister pnp 9014 x 1

op LM393 x 1

YS-LDV7 voice recognition x 1

motor x 1

toy gun x 1

Here is the scheme

microphone --> analog to digital detection circuit --> pulse signal -- > wikit sound positioning

YS-LDV7 voice recognition ---> level signal -- > wikit read

Finally, wikit controls motor by using SW spi interface

Video Results

Here is the circuit for analog to digital detection circuit. It would take the analog input and output pulse when sound is beyond a specific threshold
