LiPo (lithium polymer) batteries, especially cars, ships, etc. .. many models used in the cells are 3.7v because three or more coupled in series to the proper voltage is being achieved most widely used package 12V ones for this three lithium-polymer lipo battery series is connected but in series of batteries balanced charging required for this balance or balancing charge are circuits this circuit is in addition to battery voltage condition used to monitor connected to the batteries any 3v falls under the circuit buzzer sound is giving.

Simple Led circuits Led projects
Electronics beginners, those who are keen know usually the first spark Audio (amplifier circuits, etc.) or light (LED effects, etc.) applications people cezbe would personally my başlangıg a friend of mine his amp circuit vision began with 🙂
A plurality of LEDs simple transistor circuit 555, and realized by integrated logic gate. Two-color LED lighting circuits, LED flasher, RGB LED applications, LED game circuits and more: LED will be connected to the resistance of the ready-calculated tables, led calculations, LEDs links about the way the information in the schemes can be useful.
