Ultrasonic + RGB LED + Thermistor + DC motor 1.Write an Arduino program where the Thermistor reads in the temperature measurements.
2.When the temperature rises above the threshold set by you, the DC motor and the RGB LED are turned ON.
3.Finally, program the ultrasonic sensor to turn OFF the RGB LED and the DC motor when you pass your hand over it.

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
