/**************************************************************************/<br />
void setup()
{
pinMode(redPin, OUTPUT); // sets the redPin to be an output
pinMode(greenPin, OUTPUT); // sets the greenPin to be an output
pinMode(bluePin, OUTPUT); // sets the bluePin to be an output
}<br />
`
RGB LED Example
`
void loop() // run over and over again<br />
{<br />
// Basic colors:<br />
color(255, 0, 0); // turn the RGB LED red
delay(1000); // delay for 1 second<br />
color(0,255, 0); // turn the RGB LED green<br />
delay(1000); // delay for 1 second<br />
color(0, 0, 255); // turn the RGB LED blue<br />
delay(1000); // delay for 1 second
// Example blended colors:<br />
color(255,0,0); // turn the RGB LED red<br />
delay(1000); // delay for 1 second<br />
color(237,109,0); // turn the RGB LED orange<br />
delay(1000); // delay for 1 second<br />
color(255,215,0); // turn the RGB LED yellow<br />
delay(1000); // delay for 1 second<br />
color(0,255,0); // turn the RGB LED green<br />
delay(1000); // delay for 1 second
`
RGB LED Example
`
color(0,0,255); // turn the RGB LED blue<br />
delay(1000); // delay for 1 second
color(0,46,90); // turn the RGB LED indigo
delay(1000); // delay for 1 second
color(128,0,128); // turn the RGB LED purple<br />
delay(1000); // delay for 1 second
}<br />
/******************************************************/<br />
void color (unsigned char red, unsigned char green, unsigned char blue) // the color generating function<br />
{<br />

SCHOCK SWITCH
SCHOCK-SWITCH-Example
``` const int vibswPin = 8; //the Vibration Switch attach to const int ledPin = 13; //the led attach to int val = 0; //initialize the variable val as 0 // void setup() { pinMode(vibswPin,INPUT); //initialize vibration switch as an input pinMode(ledPin,OUTPUT); //initialize ledPin switch as an output } /*/
```
SCHOCK-SWITCH-Example
`
void loop()
{

if(val == HIGH) //without vibration signal
{
digitalWrite(ledPin,LOW); //turn off the led
}
else

I2C(2019-11-12)
Inter-Integrated Circuit
2C is a serial protocol for two-wire interface to connect low-speed devices like microcontrollers, EEPROMs, A/D and D/A converters, I/O interfaces and other similar peripherals in embedded systems. It was invented by Philips and now it is used by almost all major IC manufacturers.
SPI(2019-11-12)
The Serial Peripheral Interface (SPI) is a synchronous serial communication interface specification used for short-distance communication, primarily in embedded systems.
One Wire(2019-11-12)
1-Wire is a device communications bus system designed by Dallas Semiconductor Corp. that provides low-speed (16.3 kbps[1]) data, signaling, and power over a single conductor.
1-Wire is similar in concept to I²C, but with lower data rates and longer range. It is typically used to communicate with small inexpensive devices such as digital thermometers and weather instruments. A network of 1-Wire devices with an associated master device is called a MicroLAN.
device communications bus system
Device communication busses will be used, if you will connect many sensors directly to the microcontroller like arduino.
