Base Shield V2

pir

Arduino Uno is the most popular Arduino board so far, however it is sometimes frustrating when your project requires a lot of sensors or Leds and your jumper wires are in a mess. The purpose of creating the Base Shield is to help you get rid of bread board and jumper wires. With the rich grove connectors on the base board, you can add all the grove modules to the Arduino Uno conveniently! The pinout of Base Shield V2 is the same as Arduino Uno R3.

Compatible Boards​

The Base Shield is tested and fully compatible with following boards:

  • Arduino Uno(all revisions)/Seeeduino(V4&V4.2)
  • Arduino Mega/Seeeduino Mega
  • Arduino Zero(M0)/Seeeduino Lorawan
  • Arduino Leonardo/Seeeduino Lite
  • Arduino 101
  • Arduino Due 3.3V
  • Intel Edison 5V
  • Linkit One
Attention

The default I2C pins of Grove Base Shield are D70/D71, but the default I2C Wire of Arduino DUE is defined as D20/D21, so when using both together, you will not be able to use the I2C pins of the expansion board properly if you use the Wire definition, you need to use Wire1.

Software​

  • Step 1. Copy below code to Arduino IDE and upload to Seeeduino.
const int button = 2;       // connect a button
const int buzzer = 3;       // connect a buzzer
void setup()
{
    pinMode(button, INPUT); //set button as an INPUT device
    pinMode(buzzer, OUTPUT);   //set LED as an OUTPUT device
}
void loop()
{
    int btn = digitalRead(button); //read the status of the button
    digitalWrite(buzzer, btn);
    delay(10);
}
  • Step 2. Press the button and we will hear the buzzer.
