  • DQ0, DQ1 and DQ2 outputs will be passive after the flour, water and yeast intake is complete when the system is on. These digital outputs are connected to the Not block for producing a high-level signal.
  • After the flour, water and yeast are taken, the And gate output will be activated and the mixing will start and the message will be sent after the mixing time is over.
