Can you suggest me IoT projects for begineers.

Hello,

i am new to this arduino world and i wanna develop my skills very fast. I want to learn IoT using arduino.
Can you help me and suggest me any begineer IoT projects with source code?

How about arduino wifi control mood light. using RGB LED.

You could connect a temperature sensor and send the readings to IoT. You could then take your girlfriend for a dirty weekend in Acapulco and bore her senseless while you check the temperature on your phone.
