Led Matrix With AT90S2313 Microcontroller Circuit LED ball physically assembled in a matrix of dimension 20 Rays and 7 LEDs. LEDs are governed microcontroller and two decoder K155ID10. Operating current 80mA decoders, this is enough to connect the LED matrix in the dynamics of directly between the microcontroller and decoders, excluding transistors, the brightness of [...]
Led Flasher with IC 555 Circuit A dual tandem flashing light circuit powered by a 9 volt battery, This circuit is powered by a 9 volt battery, suitable for warning lights on a tall structure. (Personally, I can’t recommend you buy anything but the Rollins Railroad Designs kit; for $4.00 you can’t go wrong. The [...]
AT90S2323 Microcontroller 418MHz RF Transmitter 2 Channel The transmitter is constituted by AT90S2323 microcontroller and TLP434 RF transmitter module at 418MHz. I have designe the transmitter for more battery economy and safe transmition of the data. * The battery economy is made it by the use of powerdown mode of AVR. In this case the [...]

Electronic Lock SmartCard4 with AVR AT90S2313 lectronic lock SmartCard4 is Security arrangement activity based on AVR AT90S2313, agnate dent with ATtiny2313. Rudi Slejkovec uses Baskom AVR to abridge the code. The advantage from this activity is it has baby physic, accessible to accomplish and use. It provides added advantage to its assurance back the adapter [...]
Media Center PCs Remote Control Infrared Receiver Circuit The ambit consists of accustomed apparatus (except of ATtiny13 in some cases). The IC1 is an bittersweet receiver at 30 kHz. The T2 makes the about-face On/Off of Media Center back it gets a High akin by IC2. The K2 is affiliated at the “power switch” adapter [...]
18Watt amplifier circuit TDA2003 is a BCL (bridge amplifier is used) and deliver a car to 18W. TDA-series integrated circuits are well apreciated and used in the amplifier designs and projects. TDA audio amplifier circuits are usually manufactured in Philips and SGS-Thomson. The most commonly used IC TDA2030 is a small audio amplifier TDA7294 sets [...]
