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 [...]

This Project can be used with the three phase Induction motors. The circuit will take the full control of the motor and it will protect the motor from several faults such us over voltage and under voltage and the circuit will switch on the motor under safety conditions. The circuit was fully controlled by the [...]
Here’s a alarm clock circuit based on PIC Controlled. Two circuit boards put together a simple PIC based design comprising of two interlinked vero-board cards. The larger of the two circuit boards holds the 5V power regulator, the display processor (a PIC 16F74), the real time clock (Dallas DS1307), 3V backup battery and buzzer. See [...]
Digital LCD Thermometer Circuit At this thermometer, the IC thermo sensor (S8100) or the diode (1S1588) is acclimated as the thermo sensor. Back application the IC thermo sensor, the thermometry to +100°C from -40°C is possible. Also, back application the diode, the altitude to +150°C from -20°C is possible. Both sensors are independent in the [...]
Here’s a fire alarm circuit using LDR (Light Depending Resistor) as light sensor. It warns the user against fire accidents. It relies on the smoke that is produced in the event of a fire. When this smoke passes between a LED and an LDR, the amount of light falling on the LDR decreases. This causes [...]
