pico-remote-ir

Introduction

This is an example project of using an infrared transmitter to create wireless communication with a Raspberry Pi Pico receiving via an IR diode.

How to install

1. Make sure that your Raspberry Pi Pico is connected to computer

2. Clone repository or Download ZIP and unpack

   git clone https://github.com/nowacci/pico-ir-remote.git

   https://github.com/nowacci/pico-ir-remote/archive/refs/heads/master.zip
   

3. Using IDE (for example Thonny) move /ir_rx, config.py and main.py to your Raspberry Pi Pico

4. Done!

Breadboard

Here is list of components that you will need:

• Breadboard
• Raspberry Pi Pico
• 4 LEDs
• 4 Resistors (I use 330Ω)
• IR diode
• NEC remote
• Wires
• USB Cable

Connect all components using scheme below:

Show breadboard

Show remote

Functions

We have 3 modes of working as functions:

• remote_value - Default mode of code. By pressing 1-4 on remote you can turn on/off LEDs, 0 turns off all LEDs

• default - Mode that prints assign names of buttons on the remote control using by me

• search - Mode that prints vaules sent by remote control (good to detect new buttons/NEC remotes)

Configuration

In this section I explain how to configure code to personal use

Open main.py file and go to callback function and choose mode by comment/uncomment code like below

def callback(data, addr, ctrl):
    remote_value(data)   # default for this project
    #default(data)       # printing names of button on remote
    #search(data)        # searching for new values from other NEC remote  

def callback(data, addr, ctrl):
    #remote_value(data)  # default for this project
    default(data)        # printing names of button on remote
    #search(data)        # searching for new values from other NEC remote  

def callback(data, addr, ctrl):
    #remote_value(data)  # default for this project
    #default(data)       # printing names of button on remote
    search(data)         # searching for new values from other NEC remote
