Introduction

Multi-purpose Shield V1 is a learning board based on Arduino. No need for soldering and connection. Download directly the program to complete experiment. It is multi-purpose and we offer code libraries of all modules that have been tested. You can use them directly. There are extended ports on the shield to help you to complete other experiment.

Specification

  • Compatible with main controller on the market,such as UNO R3 and MEGA2560
  • Using two-channel LED indicator to show the working condition of program for modulating program conveniently
  • Completing external interrupt experiment by two-channel keyswitch
  • One reset button
  • Measuring temperature and humidity with DHT11 temperature and humidity sensor module
  • Using revolving potentiometer to do analog input
  • Alarming and making sound by passive buzzer module
  • Full-color LED
  • Utilizing photovaristor to detect the brightness of light
  • Do temperature measuring experiment with LM35D temperature sensor
  • Detecting infrared receiving by infrared receiver
  • 2-channel digital port(D7、D8)
  • 1-channel analog port(A3)
  • One IIC interface
  • One TTL serial port

Result

After powering on, indicator D1 is on, TX light on the board is blinking and indicator of LED13 is always on. Press SW1 to start flowing light and buzzer, and then open serial port. You can directly detect IR receiving without pressing buttons, the monitor displaying value. Press SW2 when opening serial port to start functions of DHT11, analog input,photosensitive device and LM35 testing,the monitor displaying value.
If you need to test again, please close serial monitor and press reset button to repeat above steps.
