28. Hacking your Set-top box IR remote

Hello everyone!

Today I will teach you how to hack your set-top box IR remote using Arduino. In this case, I will be using Videocon d2h IR remote. If you are unsure about how to use the IR transmitter module for making IR remote, or do not know about IR communication, please refer to my previous project about making an IR remote and controlling some LEDs with it. My previous project was designed for beginners in IR communication using Arduino.
Hacking your set-top box IR remote can be useful in emergency situations, when the remote runs out of battery or does not function properly. In my opinion, I think that the power, channel up/ down and volume increase/decrease are the important buttons of your IR remote so I have hacked them by giving these functions to the push-buttons of my IR remote.

Supplies

  • Arduino Nano
  • Solderless Breadboard
  • IR transmitter module (KY-005)
  • IR receiver module (KY-022)
  • Push-buttons (x5)
  • Resistor - 220Ω
  • Male-to-Male Jumper wires - 10 cm (x5) and 20 cm (x1)
  • Jumpers

Setup

Your setup must look somewhat similar to the one shown in the image above.

Connections

IR transmitter module (KY-005)
  • (-) - GND (Ground)
  • (S) - D3
There is no connectivity between the (+) pin and the IR LED  in my IR transmitter module.
Push-buttons
  • 01 - D2
  • 02 - D3
  • 03 - D4
  • 04 - D5
  • 05 - D6
IR receiver module (KY-022)
  • (+) - 3.3V
  • (-) - GND (Ground)
  • (S) - D11

Coding

As I already mentioned in the first section of this page, please refer to my project about making IR remote as the codes of this project are similar to that mentioned in it. Connect your IR receiver module to the Arduino Nano, go to File, Examples, IRremote library, and upload the IRrecvDump sketch. Place the set-top box IR remote in front of the IR receiver module and press each button mentioned in the first section of this page. You will see the Encoding type and the decoded IR signal printed on your Serial Monitor. Use these decoded IR signals to make your IR remote. 
If you still have any questions about the coding section, please feel free to comment below or send an email to arduinoprojectsbyr@gmail.com.

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 -...
