The 9 in 1 Multifunction Expansion Board Module (sometimes it is called HALJIA) is a versatile board that can be used for a variety of Arduino projects. It includes 9 different modules:

  • DHT11 humidity sensor
  • LM35 temperature sensor
  • Buzzer
  • Brightness sensor
  • Full color LED module
  • 2-way button module
  • 2-way LED module
  • Infrared receiver module
  • Rotary potentiometer module

This board is fully compatible with the Arduino UNO R3 and provides a convenient way to add these 9 modules to your projects without having to wire them up individually. It also has a custom high-pin design to avoid short circuits with the Arduino.

Here are some examples of projects that you can build with the HALJIA 9 in 1 Multifunction Expansion Board Module:

  • A weather station that measures temperature, humidity, and brightness
  • A security system that uses the infrared receiver module to detect motion and the buzzer to sound an alarm
  • A robot that uses the rotary potentiometer module to control its movement and the brightness sensor to avoid obstacles
  • A traffic light simulator that uses the full color LED module to display different colors

The 9 in 1 Multi-function Expansion Board Module is a great choice for Arduino beginners and experienced users alike. It can help you to save time and simplify your projects.
