BASIC DEVICES MADE WITH ELECTRONIC COMPONENTS

1.Timers
It is a device that operates for a certain period of time and then shuts itself off automatically:


-At first, the LED is off,since there is no current flowing through the base. When we push the button, current flows through the base , and the transistor is activated, and the LED turns on. The capacitor also begins to charge itself.


-When we release the button, the LED continues to produce ligh for some time, using current from the capacitor.

2.Integrated circuits
They consist of miniature electronic components.
