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.

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
[sudo] password for deepak: ********
