Arduino Multifunction Shield (HCARDU0085) : Features

This is kind of review out of marketing research as ex-willing consumer. Initially I thought that it is Made in China and has lot of sensors. Arduino Multifunction Shield has 4 digit 7 segment led display, 4 SMD led, 10k potentiometer, 3 push buttons, buzzer and lot of interfaces. It is not Made in China, it is just a costly thing with very less features. $2 would be correct price for it. This is the original company :

Arduino Multifunction Shield is good for the children. It is also ideal for low IQ adult humans.

It is basically a daughterboard with few basic electronic components including a display like TM1637 LED Display. Indeed TM1638 Display Module is far better unit. Except China, Korea, Japan none can make anything good a lower price – their average IQ is far higher. Russia makes few things great. You can build a good daughterboard with the components.

Multi function shield has :

One 4 digit 7-segment LED display module driven by two serial 74HC595
Four surface mount LED’s in a parallel configuration
One 10K adjustable precision potentiometer
Three push buttons
One Piezo buzzer

Thats it. Others are for connection (interface), they are not components :

DS18B20 temperature sensor interface
LM35 temperature sensor interface
Infrared receiver interface
Serial interface header to connect serial modules such as Bluetooth, wireless interface, voice module, voice recognition module etc

They have some snippets to give examples (how funny, they asked to give credit for these few lines) like this is for push button with computer’s serial display :

#define BUTTON1 A1
#define BUTTON2 A2
#define BUTTON3 A3

void setup()
{
  Serial.begin(9600); 
}

void loop()
{
  if(!digitalRead(BUTTON1))
    Serial.println("Button 1 Pressed!");
  if(!digitalRead(BUTTON2))
    Serial.println("Button 2 Pressed!");
  if(!digitalRead(BUTTON3))
    Serial.println("Button 3 Pressed!");
}

#define BUTTON1 A1

#define BUTTON3 A3

void setup()

{

Serial.begin(9600);

}

void loop()

{

if(!digitalRead(BUTTON1))

Serial.println("Button 1 Pressed!");

if(!digitalRead(BUTTON2))

Serial.println("Button 2 Pressed!");

if(!digitalRead(BUTTON3))

Serial.println("Button 3 Pressed!");

}

In this way, we can also sell Arduino shield combining with LED clock with traffic light with timer with some servo motor functions, rotary encoder.

China does honest business.
