Cigar Lighter Plug to USB Power Socket. This circuit is convert 12V DC source from car cigar lighter plug to become USB power sochet with 5V DC output. This circuit can be used to powering 5V electronic devices or recharge the rechargable battery from USB port. Nowadays, almost all computer systems have logic blocks for working with a USB port. A
Cigar Lighter Plug to USB Power Socket - schematic

USB port, in practice, is capable of supplying more than 100 mA of continuous electric current at 5V to the peripherals which are hooked up with the bus. So a USB port could be utilized, without having any problems, for. This is the circuit diagram of USB powered computer speaker, or it widely known as multimedia speakers for PCs. The circuit has single-chipbased design, low-voltage electrical power supply, compatibility with USB power from computer, simple heat-sinking, inexpensive, large flexibility and wide temperature tolerance. At the heart of the circuit is IC TDA2822M. This IC is, . Here the USB Sound Card circuit based on PCM2706 which dedicated for USB audio. With USB controller module inside PCM2706, there is no more additional programming to the IC. The computer system will automatically detect this circuit when connected tho the USB port. You will get stereo audio channel output from this circuit. Schematic: Components:. Here the Arduino UNO schematic diagram (click to enlarge): About Arduino UNO: The Arduino Uno is really a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 may be employed as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP. Here is a simple and easy to build circuit diagram of a 12V car battery charger: The above circuit claimed have ability to prevent battery overcharge that make electrolyte lost...
