Key sequencing logic
The following flowchart illustrates how to detect the correct key sequencing before disarming the alarm. This is one of the question in programming using flowcode. Pay attention to the breaking down of problem in programming. There is still one problem when the program is run: the timing for scanning the key status. If the delay … Read more
Electronic Control
It is very common to design electronic control circuit and I have students from doing the senior project to working in industries not quite aware of the similarity in various way to control. Not starting from a feedback control system but starting from electronic circuitry logic, it starts with sensor sensing either temperature, pressure, light, … Read more
