TV remote control Blocker Circuit – IR Remote Control Jammer – using Ic 555 and IR Leds
Just point this small device at the TV and the remote gets jammed . The circuit is self explanatory . 555 is wired as an astable multivibrator for a frequency of nearly 38 kHz. This is the frequency at which most of the modern TVs receive the IR beam . The transistor acts as a [...]
Circuit light sensor with LDR (Light Dependent Resistor)
The example circuit used in various situations, such as control lamps or other device that needs to be turned off when the daylight. It is based on LDR (Light Dependent Resistor) is a special resistor that varies its electrical resistance according to the amount of light falling on its surface. The circuit shown is easy [...]
Circuit sensor shadow (twilight) with ldr – lighting control and other applications
Serves to control a load according to the lighting in this case in the absence of the light circuit is activated. One application is good practice to light a lamp so dark, like those used in lighting systems for public lighting. The circuit is quite simple, the trimpot is used to adjust the operating point [...]
Dimmer circuit triac tic225 POWER control in loads as illumination of lamps
Dimmer with triac tic225, potency control in loads as illumination of lamps. The main component of that project is the triac that acts as a switch that determines the amount of power that will apply the lamp or other load. The potentiometer in the circuit is to vary the potency supplied by the triac. On [...]
