Overview of this book

The mission of this book is to integrate technology with the tools that children already use for crafts so that they feel that the technology is an extension of their playtime. We use coding, sensors, and micro-controllers integrated with art and craft supplies, origami, and Playdough. There are 10 fun-filled chapters that talk to children directly, and give clear instructions for non-technical parents too. We use Arduino as the controller of choice due to its easy availability and large community. By the end of the book, children will comfortably be able to set up their Arduino, read and understand code, manipulate code, and ultimately write their own code for projects. They will also be able to use basic sensors and know how components connect to each other. All the learning takes place with lots of colorful pictures and the circuits are neatly presented using wiring.

The safe

You now have all the know-how to build our safety box!

Let's start with the code:

//Initializing a variable to store the value of the button state 
int lidState = 0; 
int keyState = 0; 
int lidPin = 2; 
int keyPin = 3; 
int alarmPin = 9; 
// the setup function runs once when you press reset or power the board 
void setup() { 
  // initialize digital I/O pins 
  pinMode(lidPin, INPUT); 
  pinMode(keyPin, INPUT); 
  pinMode(alarmPin, OUTPUT); 
// the loop function runs over and over again forever 
void loop() { 
  lidState = digitalRead(lidPin); 
  if ( lidState == LOW ) 
    keyState = digitalRead(keyPin); 
    if ( keyState == HIGH ) 
      digitalWrite(alarmPin, LOW); 
      digitalWrite(alarmPin, HIGH); 
    digitalWrite(alarmPin, LOW); 

We start by storing the pin numbers in variables...
