Infrared remote control receiver for Media Centers
Some time ago, a media center box was created to replace a DVD player, satellite receiver, VCR, and PlayStation 2 with a single device. A Core 2 Duo processor system successfully replaced all these electronic devices. However, a remote control...
off infrared remote control schematic
According to the note on the schematic, IC-2 is a 74HC74 TTL chip. Refer to the data sheet for details regarding pins 7 and 14. The note for IC-3, located lower on the schematic, indicates it is an AC optocoupler...
One infrared burglar alarm circuit
The infrared alarm system utilizes an infrared LED that emits invisible light. When this light is obstructed by an object, it triggers an alarm. The system comprises an infrared light-emitting circuit and a receiving circuit. The light-emitting diode (LED) is...
Remote-Control Analyzer Circuit
A schematic diagram for the remote analyzer is presented. The circuit is powered by a simple 5-V supply, which includes components such as PL1, SI, Tl, a bridge rectifier formed by diodes D1 through D4, capacitor CI, and a standard...
Infrared automatic faucet circuit diagram
The circuit consists of the following components: (1) An infrared emitter which utilizes a multi-harmonic oscillator based on a 555 timer circuit. The oscillation frequency is determined by the values of RP1, R1, and C1, resulting in a frequency of...
DIY computer infrared interface
A and B are two common contacts, along with an outline drawing and pin definitions. C refers to the shape of the infrared emission tube, including its pin definition and schematic symbol. CD4069 provides the pin definitions for the inverter...
Infrared-Led based Wireless Data & Voice Communication withCircuit
The objective of this project is to design a circuit for an electronic infrared communication system, develop innovative ideas for implementing this circuit, and study the circuitry along with various components such as DTMF generators, DTMF decoders, operational amplifiers, and...
Simple TV Remote Control Jammer
This circuit disrupts the infrared receiver in a television by generating a continuous signal that interferes with the remote control signals, preventing the TV from recognizing channel changes or other commands. This allows for uninterrupted viewing of a chosen program...
Infrared Proximity Detector Alarm
This circuit can be constructed using readily available low-cost components, some of which may be found in a junkbox. The specified value of 22 ohms for resistor R1 results in an average current of approximately 65 mA through the infrared...
