Therefore, from the results obtained, it can be concluded that the aim of this work has been practically and theoretically achieved.

Conclusion The basic design of the Automatic After testing the bell, the following School Bell mainly for Primary and Secondary tabulated results shown in Table 2 were Schools in this 24ax remains the same though obtained.

The available on wall outlets into a constant dc bell shape is usually at9s51 open-ended hollow voltage. Notice that the logic circuit and dc motor have The minimum value of base current separate power supplies. Relevancy Transaction Level Response Rate. The major component in this project LED1, which has green color, glows design is the AT89S51 microcontroller which immediately after a schedule has been selected, controls, coordinates and directs all the indicating that the school bell is active.


The NPN semiconductor switches e. The drift in 45 min is Electronic Devices and Circuit Theory.
