2. As the experience shows,giving to students only theoretical knowledge is barren activity and does not have a desired result, especially if it relates to the engineering field. Almost all of the people working in this field goes to the conclusion that the introduction of the principle of working together with practical training is an important part of education. But it is also important to know what type a laboratory course will be and what topics will it include.

3. We can plan the following steps as learning the basic skills of the installation and design

4.  The high accuracy of timing  Generating the rectangular pulses  Common attribute of both analog and digital electronics  Electronic device with relatively simple structure  Its working principle and operation is simple to learn

5. Constructor -Important educational resource. We will put in it the 555 timer, the necessary details of the scheme and its theory into Georgian language. This will be a big contributor to the development of the group as well as the independently studying. Constructors can be designed for mass production and distribution throughout Georgia.

6. This package will be a teaching tool for teacher.There will be placed: 1. Printed circuits 2. Already assembled mounting schemes 3. Costructors 4. Learning Resources (theoretical material) It will better the package to be accompanied by the personal computer,which will be used as an oscilloscope by the teacher. This will increase students' interest in the subject.

7. Also available English-language material, which creates a clear impression about the 555 Timer:Learning 555 (1).docxLearning 555 (1).docx
