6 channel IR remote with PIC 16F84

Description: This project is a remote control system based on a PIC and a universal remote controller for TV, named SIMPLEX. The IR signal of a specific remote controller is received from an IC receiver (SFH 505 or similar) and sent to the PIC. The inside program decodes the algorithm and switches 6 output ports and the corresponding relays. You can use it to control 6 appliances of your room such as lamp, radio, Hi-Fi, TV, computer, and so on. The range is great about 10 meters. Obviously, you have to get the right remote controller; I used the above universal TV remote and programmed it with the 2242 code, which corresponds to the code of some Sony and Mitsubishi TVs. I took the decoding algorithm from tanzilli.com and picpoint.com.

The remote control system utilizes a PIC microcontroller, which serves as the core processing unit. The system begins with an infrared (IR) signal being transmitted from a universal remote control. The SFH 505 IR receiver captures this signal, converting it into an electrical signal that can be interpreted by the PIC microcontroller. The choice of the SFH 505 is crucial as it is designed to receive modulated IR signals effectively, ensuring reliable communication with the remote.

The PIC microcontroller is programmed to decode the incoming IR signals based on a specific algorithm. The algorithm is tailored to recognize the commands associated with the 2242 code, which is compatible with various brands, including Sony and Mitsubishi. Upon decoding the command, the microcontroller activates one of the six output ports. Each port is connected to a relay capable of controlling a different appliance. The relays act as switches, allowing the microcontroller to turn on or off devices such as lamps, radios, Hi-Fi systems, TVs, and computers.

The system's operational range is approximately 10 meters, providing flexibility in controlling devices from a distance. The use of a universal remote control simplifies the user experience, as it eliminates the need for multiple remotes for different devices. The implementation of this remote control system is ideal for home automation projects, enhancing convenience and control over household appliances.

For further development, considerations may include additional features such as feedback mechanisms to confirm device status, integration with smart home systems, or expansion of the number of controlled appliances. The modular design allows for easy upgrades and modifications, making it a versatile solution for various applications.This project is a remote control system based on a pic and an universal remote controller for TV, named SIMPLEX.
