26. DIY IR Remote and IR Remote controlled LEDs

Hello everyone!

Today I will be teaching you how to make a DIY IR Remote and IR Remote controlled LEDs. For this project, you will be needing both Arduino Uno and Arduino Nano. Before starting this project, make sure that you install the IRremote Library by Ken Shirriff from your Arduino IDE software.
Please visit this website, to learn about IR communication in detail. Refer to the 'Coding' section in this page to understand how to start this project.

Supplies



  • Arduino Uno
  • Arduino Nano
  • Type A/B USB cable (for Arduino Uno)
  • Type A to Mini B USB cable (for Arduino Nano)
  • Solderless Breadboard (x2) - Mini and Full-size
  • IR transmitter module (KY-005)
  • IR receiver module (KY-022)
  • Resistors (x5) - 220Ω
  • Push-buttons (x5)
  • LEDs (x4) - Red, Green, Yellow, and Blue
  • Male-to-Male Jumper wires (x21) - 10cm
  • 3 pin Female-to-Female Jumper Wires (x2) - 70cm
  • Jumpers (x5)

Setup



Your setup must look somewhat similar to this. You can also use a PCB breadboard to make your DIY IR remote.

Connections

IR transmitter module
  • (+) - 3.3V
  • (-) - Ground (GND)
  • S - D3
IR receiver module
  • (+) - This pin has no connectivity with the IR LED
  • (-) - Ground (GND)
  • S - D11
Push button
  • Ground (GND)
  • 01 - D4
  • 02 - D5
  • 03 - D6
  • 04 - D7
  • 05 - D8
I have not connected the push buttons to the 10kΩ resistor. You can learn more about this, here.
LEDs
  • Cathode - Ground (GND)
  • Red - D7
  • Green - D6
  • Yellow - D5
  • Blue - D4

Coding

First of all, assemble your components and they must look similar to the setup in the images from the last section. Go to Examples, open IRRemote Library, and select IRrecvDemo to get decode the IR signals sent by an IR remote and to discover its type of IR transmission protocol. Take out an IR remote, place the IR LED right in front of your IR receiver module to avoid IR noises, and press each button on your remote to see the data send by the IR signals.
Decoding the IR signals and discovering the IR transmission protocol can help us to prepare the sketch for our DIY IR remote. To check whether the connections are correct with your IR transmitter module, go to examples, open IRremote library, and select IRsendDemo. Place your phone camera above the IR LED and upload the code to your Arduino Uno. You should see the IR LED blinking if your connections are correct.
My Midea Fan remote uses NEC IR transmission protocol, and I have used the irsend.sendNEC function in my sketch. Refer to this website to learn more about coding for IR transmitter and receiver modules. 
If you need any help with the coding, please feel free to comment below or send an email to arduinoprojectsbyr@gmail.com, and I will guide you.

Final Look

51. Buzz wire game using Arduino

Hello everyone! This is my first Arduino project in 2020 and it is going to be a fun and simple project. You would have heard of the Buzz Wire, a steady hand game, and today you will be learning to make one using Arduino. Hardware components used in this project Arduino Nano USB Type A to mini B cable (for Arduino Nano) Solderless Breadboard - Mini and Full-size LEDs (x2) - Green and Red Resistors (x2) - 220 Ω  Active Buzzer module (KY-012) LCD display module with I2C interface - 16x2 Male-to-Male Jumper wires (x4) - 10cm Female-to-Male Jumper wires (x5) - 20 cm Jumpers (x5) - to reduce the usage of wires Copper wire  Tape (or any form of insulation)  Setup Your hardware setup must look somewhat similar to the ones in the images above. The beginning and end of the copper wire maze must be taped to prevent conductivity between the wire loop and maze. Connections LCD display module with I2C interface GND - Ground VCC - 5V SDA - A4 SCL - A5
