Multi function Shield for Arduino Uno R3 Microcontroller

Multi function shield for arduino uno r3 expansion board

This multi function shield is designed based on arduino uno r3 micro controller development board.

The Multi-function Shield has the following features:

1. Seamless compatibility with mainstream controllers on the market, such as UNO (2009) and MEGA 2560.

2. 4 LED indicator lights – LED indicators are very important in real engineering projects. They can directly display the working status of the program, making debugging much easier.

3. DS18B20 temperature sensor interface for temperature measurement experiments. (Note: DS18B20 sensor is not included in the price and must be purchased separately if needed.)

4. LM35 temperature sensor interface for temperature measurement experiments. (Note: LM35 sensor is not included in the price and must be purchased separately if needed.)

5. 3296 precision adjustable potentiometer, providing analog input. It can be used to control LED brightness, adjust servo angles, or simulate variable voltage input.

6. Integrated infrared receiver interface, suitable for experiments with most IR remote controllers. (Note: The integrated receiver is not included and needs to be purchased separately.)

7. 4-digit seven-segment display driven by 74HC595, which saves I/O pins and helps learn SPI communication. It can be used for display experiments such as temperature, voltage, counting values, etc.

8. Three independent buttons and one reset button, suitable for button control experiments and simple human–machine interface applications.

9. Buzzer module for sound experiments such as alarms or tone generation.

10. Bluetooth, wireless interface, voice module, and speech recognition module interfaces, enabling wireless communication experiments.

11. Servo motor interface for easy servo control.

12. Infrared detection interface, convenient for connecting infrared sensors to implement applications such as people counting.
