Ir Receivers
Before using this or a similar device, their data sheet should be read carefully and any power supply recommendations should be followed to prevent false output pulses. The receiver module used for this test worked very well under all levels...
Remote Jammer
This circuit can jam the remote handset used to operate a TV. As long as the circuit is active near the TV, the remote handset cannot change the channels. The circuit is a simple IR transmitter operating at 38 kHz,...
ir receiver circuit
This is a straightforward and easy-to-construct infrared (IR) receiver circuit. The circuit utilizes only a few components and is capable of receiving a 38 kHz carrier signal. The operation of this circuit is simple; whenever the IR LED detects a...
Optical communication system
The circuit modulates the light emitted by an LED using either a crystal microphone or a loudspeaker output. To achieve maximum range, the optical system must operate efficiently. A convex lens or a concave mirror can be utilized to transform...
Ir-transmitter
The transmitter consists of an oscillator that drives a high-output infrared (IR) emitting diode. The oscillator is a simple multivibrator circuit that provides an output with a mark-to-space ratio ranging from 15 to 1000 at a frequency of 1 kHz....
