11. Using Flame sensor and two LEDs to detect flame

Let me give you a glimpse of this project.
In this project, the flame sensor will detect a flame and its proximity to light up two LEDs. There will be two coloured LEDs: Red and Yellow. The Red LED will light up when the flame is near the sensor and it has a larger size, while the Yellow LED will light up when the flame is within 20 cm from the sensor.


Supplies:

  • LEDs - Red and Yellow
  • Resistor - 220 Ω (x2)
  • Flame sensor module 

  • Arduino Uno R3
  • Solderless Breadboard - Mini
  • Jumper Wires

Setting up your hardware





Connections:



  • Flame sensor - A0
  • Anode (Red) - D10
  • Anode (Yellow) - D5
  • Cathode (LEDs) - Ground (GND)



Coding

With Serial Monitor:

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

71. Buzz Wire Game ( Version 2.0 ) using Arduino

Hey Everyone! I hope that everyone's safe during this pandemic. Today I am going to explain you about the second version of my Buzz wire game. People who are bored of staying indoors can find this game pretty interesting and fun to play.  If you are a beginner, you can start off with my first version of this project :  51.

86. RFID Health tag (Arduino and Python)

 Hey everyone, Sorry I have not uploaded in a while. Today, I will be sharing an interesting project with all of you. This RFID Health tag project is useful when it comes to keeping track of vaccinated individuals, their biodata and their health conditions and medications. For this project, you will be needing Arduino and Python. Read on further to see how I did this project. Hardware components used in this project Arduino Uno Solderless Breadboard - Half+ MRFC522 RFID reader RFID key tags (x5) Push-buttons (x2) Male-to-Male Jumper wires (x12) USB Type A/ B cable (for Arduino Uno) Software required Arduino IDE - latest version recommended Python 3.8 Schematic MFRC522 RFID reader SDA/ SS - D10 SCK - D13 MOSI - D11 MISO - D12 IRQ - Not connected GND - Ground RST/ RESET - D9 3.3V - 3.3V Push-buttons Submit button - D4 Retrieve button - D5 Coding Arduino For this project, you will be using the following libraries: MFRC522 by miguelbalboa -  https://github.com/miguelbalboa/rfid SPI - In-bu
