What is advantages of programmable control?Show answer
This is why microcontrollers are used in almost all modern products - washing machines, toys, alarms - where flexible, complex control is needed.
What are programming with flowcharts?Show answer
A microcontroller program is often planned as a flowchart (sequence and decision symbols) and then written in a simple language or flowchart-based software. The flowchart decides the order of actions and the decisions the controller makes, linking directly to the digital-control topic.
What is the resistor-capacitor timing circuit?Show answer
The length of the delay depends on the resistor and capacitor values:
