On-off Infrared Remote Control circuit
The proposed circuit design features a universal infrared receiver that can decode signals from various remote controls, allowing for seamless integration with existing devices. The core component of this design is a microcontroller, which processes the received infrared signals and triggers a relay to control the light's power state.
The infrared receiver is connected to the microcontroller's input pin, which is programmed to recognize specific signal patterns corresponding to the on/off commands of a wide range of remote controls. The microcontroller is powered by a standard DC power supply, ensuring consistent operation.
A relay is used to control the light circuit, providing electrical isolation between the low-voltage control side and the high-voltage lighting circuit. The relay is rated appropriately to handle the load of the light fixture, ensuring safe operation. Additionally, a flyback diode is implemented across the relay coil to protect the microcontroller from voltage spikes generated when the relay is deactivated.
To enhance user experience, an LED indicator can be incorporated into the design, providing visual feedback on the status of the light (on or off). This LED can be connected to another output pin of the microcontroller, which will be toggled in sync with the relay operation.
Overall, this infrared remote-controlled light switch circuit offers a versatile solution for controlling lights in a home environment, providing convenience and ease of use while eliminating the need for multiple specialized switches.Most homes today have at least a few infrared remote controls, whether they be for the television, the video recorder, the stereo, etc. Despite that fact, who among us has not cursed the light that remained lit after we just sat down in a comfortable chair to watch a good film?
This project proposes to solve that problem thanks to its original approach. In fact, it is for a common on/off switch for infrared remote controls, but what differentiates it from the commercial products is the fact that it is capable of working with any remote control.. 🔗 External reference
