"DIY Remote-Controlled Multi-Bulb Setup"

Dear viewers, This project is a simple yet functional remote-controlled AC light system. It includes a remote with 4 buttons and a receiver circuit . The system allows precise control over three AC bulbs. Using this setup, you can toggle any of three bulb or combination of bulbs ON or OFF, providing flexibility and convenience.

1. Features

1. Independent control of up to 3 bulbs.
2. Turn on/off any bulb individually or in combination.
3. Ability to:
4. Turn on any 1, 2, or all 3 bulbs.
5. Turn off any 1, 2, or all 3 bulbs.
6. No specific button press order required in Remote.
7. Simple setup with labeled connections

List of Components ( Here i listed the image of some components . you need some more components than here listed)

4.Image of 3D view of PCB

The receiver circuit uses the CD4017 IC to decode the IR signals and control relays. Each signal triggers a specific relay for bulb operation. Here attached files are,

> After pcb construction you can make proper enclosure with 3d printer or with any distribution case and fix components with their responsible connection. You can add power indicator and indicator to lights to every 3 outputs to identify which are turned on and off.

1. NAMES OF THE PARTS

1. Output ports ( 3 outputs for 3 Lights)
2. Fuse
3. Power supply port for Receiver
4. IR-Receiver ( Do not hide the part from IR signal )
5. Power indicator for whole receiver circuit
6. Remote controller
7. Power indicator for 3 light outputs

Showcase the working project. Ensure to demonstrate:

1. Turning individual bulbs ON/OFF
2. Using combinations of buttons to toggle multiple bulbs

Conclusion

1. This project is a versatile and efficient way to control multiple AC devices. Its simplicity and ease of construction make it perfect for DIY enthusiasts and beginners. To modify this circuit with more count of lights you want increase the quantity of CD4017 IC , Relay and diodes mainly. Every bulbs need one relay here.
