Iroutlet

IrOutlet

IrOutlet is an 8-port power outlet. Each power outlet can be switched on or off using an IR remote.

Design details

A TSOP4836 IR receiver converts the IR light into a bit stream. This bit stream is decoded by a PIC16F15325 microcontroller. When the IR signal is decoded, the microcontroller performs an action if the signal matches a supported IR address/command listed below:

Notes

1. Address 0b00101 corresponds to the address of a Marantz remote control I had available.

2. Below are some oscilloscope captures measured at the output pin of the TSOP4836 while using the Marantz remote control:
   

Development tree

The project consists of three major folders:

1. Mplab

This folder contains the bare-metal code for the Microchip PIC16F15325 controller. MPLAB X IDE or VSCode with the MPLAB extension can be used as the development environment (using the free XC8 compiler).

Major implementation files:

• rc5.h: RC5 decoder API
• rc5.c: RC5 decoder implementation
• interrupts.c: TSOP4836 and timer interrupt handlers
• main.c: Controller setup and IR handling

2. KiCad

   This folder contains the IrOutlet schematic and PCB design.

   • The schematic consists of two major parts:
     1. The controller:
        
     2. The relay driver:
        
   • The components are laid out on a single-sided PCB:
     1. Component layout:
        
     2. Bottom mask:
        

3. FreeCAD

   This folder contains the 3D enclosure model for the IrOutlet.
