Dim Those Lights Remotely! Use this receiver for a wall mounted light dimmer in place of a standard light switch. Uses one channel of the 15 channel K8049 IR remote control for light dimming function. Use separate K6712s for different lighting circuits in the same room or throughout the house and assign different channels for [...]

This circuit receives the signal from a IR remote control, like those used to control your TV or DVD player and allows the signal to be repeated in another location. To get a 40Khz carrier requires an output to be toggled on and off 40,000 times a second, which means the code needs to execute [...]

This encoder can generate up to 19,683 codes from 9 address lines by detecting 1,0, or open circuit. To initiate the transmit sequence, pin 14 should be pulsed low. The encoder will now output on pin 15 a data stream representing the condition on each of the address/data pins in turn and then repeat the [...]
