Notes

We have worked with some different components to raise a little curiosity and interest in you
how things work What we have done is very basic stuff, but it can be good and sit
and clarify that in groups, how the different components affect each other and how important
that is, they are coming in the right order.

The difference between control and control technology is that when sending a signal or voltage, it is transmitted
directly to an appliance without measuring the result eg that you press a switch, pull a lever
or manually braking a car. If the car has an automatic system that causes the car to brake itself is
This is an example of regulatory technology.
There are different types of control technology. One of them is program-controlled control technology, where the device is controlled
an automatic program that in turn sends signals to different parts in eg. a washing machine
or a dishwasher. Feedback-based control technology is another type of control technology. difference
between program-controlled and feedback-controlled control technology is to care for program-based control technology
do not sign the program as to what results it will be, but it will continue until all parts of the program
is implemented. Feedback-based control technology, on the other hand, uses different sensors to measure
results. The thermostat in an oven is a simple type of feedback control, where you set it
the temperature you want. When the oven reaches the desired temperature, the thermostat turns off the power
the heating elements, and also if the temperature drops to the desired position, the thermostat releases
power again. A lamp with dusk sensor is another type of feedback-controlled control technology, there
A lamp will light up automatically when it gets dark. Sensitivity can be set with an electric
resistor sitting in the dusk sensor and called potentiometer.

Control technology can also provide increased security and reduce the risk of e.g. a nuclear power plant, then a human
Mistakes can be devastating. Even the technology can go wrong sometimes and important functions have to be done
double or triple control systems that control each other.
Regulatory techniques are usually effective from an environmental point of view. With control technology you can control and regulate b. A
The heat in homes, so that no more energy is consumed than necessary.
