This is a basic electronic kit based on LM358. The LM158 series consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.
Application areas include transducer amplifiers, dc gain blocks and all the conventional op-amp circuits which now can be more easily implemented in single power supply systems. For example, the LM158 series can be directly operated off of the standard 3.3-V power supply voltage which is used in digital systems and will easily provide the required interface electronics without requiring the additional ±15V power supplies.

About the kit: The light changes from bright to dark, and then gradually changes from dark to bright, feeling like a person is breathing. Widely used in digital products, computers, audio, automotive and other fields, has played a very good visual decorative effect.
