seeed studio Base Shield V2 User manual

Base Shield V2
Arduino Uno is the most popular Arduino board so far, how ever it is sometimes frustrating w hen your project requires a lot of sensors or Leds and your jumper
w ires are in a mess. The purpose of creating the Base Shield is to help you get rid of bread board and jumper w ires. 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, how ever Arduino Uno is
not the board one that the Base Shield V2 is compatible w ith plenty of boards.
Version
Product Version Changes Released Date
Base Shield V1.2 Initial Oct 2011

Intel Edison 5V
Linkit One
!!!Note
The boards are not listed above mean that it might have chance to w ork w ith the platform board how ever requires extra w ork such as jump w ires or rew riting the

code. If you are interested in digging more, w elcome to contact [e-mail].

Step 4. Plug Base Shield into Seeeduino.
Step 5. Connect Seeeduino to PC through a USB cable.
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 w e w ill hear the buzzer.
