Hot Warning Machine
For this project, you can control the speed of light. When your hand goes near the hot water, the colorful LED light will speed up the peace of shining, and when you move your hand further away the light will shine slower. This can be used to warn people to stay away from the hot water.

Supplies
Materials you will be needing ...
-Breadboard -Arduino Uno x1
-LED lights x9 ( 3 Red, 3Blue, 3 Green LEDs)
-Jumper wires x12
-Resistors*11 x9
-200-ohm resistors x1
-sensor
Build You Circuit
1- plug 9 wire from digital 9 to digital 1 then plug them
2- on the other side of the jump wire, plug all of them into A (I plug it from 34 to 49, between them I had leave a space so it won't get too crowded)
3- beside each jump wire, plug in the 9 resistors
4- besides the resistors, plug in the LED lights to positive
5- plug a wire from power 5v to negative
6- plug 200-ohm resistors from negative to B
7- plug a wire from GND to positive
8- connect two from 11 and 12 to D
9- plug 2 wires from positive to C
10- plug the sensor from 19 to 22
