infrared ir receiver
The operation of this receiver is analogous to human perception. Humans perceive colors and respond based on what they observe. Similarly, phototransistors react to the intensity of infrared light directed at them. The key distinction is that humans possess a...
Design your Circuit IR Transmitter
Most consumer electronic devices utilize infrared remote controls for convenient operation. The carrier frequency of these remote controls typically ranges from 36 kHz to 38 kHz. Control codes are transmitted to the device's receiver in a serial format, which is...
ir volume control
The television screen used at home features built-in speakers; however, since it functions as a computer display, it lacks an infrared receiver. This limitation prevents volume adjustment using the TV receiver remote. A recent acquisition of Stellaris LaunchPad development boards...
Infrared Detector Circuit with PID20
This infrared detector circuit utilizes a passive infrared detector component, PID20, which converts heat radiation into electrical impulses. The output voltage of the PID20 increases when an object approaches, provided that the object is warmer than the surrounding environment. The...
Infrared Remote Controls
This circuit enables the control of any equipment operating at 115 volts AC. It utilizes the Radio Shack infrared receiver module (MOD), part number 276-137, which can also be sourced from other suppliers listed on the Links page. The MOD...
reflected infrared light switch
Infrared light reflected off a finger is used to activate this switch circuit. Drawing only 30 µA from a 3 V supply, this circuit will detect a human finger with a range of about 1 inch. The sensor uses an...
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,...
tiny remote for irobot roomba using pic12f629
The Tiny Remote is a compact infrared remote control featuring only two buttons designed to operate an iRobot Roomba. It emits three different infrared signals.
The Tiny Remote is designed for simplicity and ease of use, making it an ideal accessory...
TV Remote Control Jammer
This is a simple circuit that anyone can create for enjoyment. The project originated when there was an attempt to control a TV using the serial port of a computer. It took only a few minutes to grasp the basic...
