Smart Light using Arduino

While working on the regular projects in office, I have joined SAP Ariba IOT Group where we try out few things which can solve some problem which could be really helpful.

I am also trying to use Raspberry Pi, Arduino and other platforms. 

Recently i have tried to build a smart light, which I want to fix it to my study table now. :-)

Circuit:
I have picked the circuit from internet which explains about the connectivity of different components.

Circuit Diagram

Demo Video:
Here is a short video about it.



Hardware Components:

Arduino Uno	1
Relay Module	1
PIR Motion Detector Sensor Module	1
Connectors/Jumper Wires	6
Power Cable	1
Power adaptor for Arduino Uno	1
Light	1

Software Components:

Arduino IDE

1

Smart Light Code

Code:

	int pirSensor = 6;
	int relayInput = 8;
	void setup() {
	// put your setup code here, to run once:
	pinMode(pirSensor, INPUT);
	pinMode(relayInput, OUTPUT);
	}
	void loop() {
	// put your main code here, to run repeatedly:
	int sensorValue = digitalRead(pirSensor);
	if (sensorValue == 1) {
	digitalWrite(relayInput, LOW);
	delay(5000);
	digitalWrite(relayInput, HIGH);
	}

Troubleshoot:
While uploading the code there was an issue with PORT( /dev/ttyACM on ubuntu) read/write permission
Following commands helped:

deepak@deepak-B570:$ ls -l /dev/ttyACM*
crw-rw---- 1 root dialout 166, 0 May 12 19:21 /dev/ttyACM0

deepak@deepak-B570:$ ls -l /dev/ttyACM*
crw-rw---- 1 root dialout 166, 0 May 12 19:21 /dev/ttyACM0

deepak@deepak-B570:$ sudo chmod a+rw /dev/ttyACM0
