Use the temperature sensor to calculate the ambient temperature. Make the use of DC motor and driver. Code your circuit such that when the temperature increases, LED turns ON and DC motor starts spinning. Here, motor will work as a Fan. The circuit connections will be quite tedious. Components required: DC motor Temperature sensor Motor driver LED Jumper wires For coding part, you just have to combine parts of code which we discussed in our session. Use the code from temperature sensor circuit to convert and calculate the temperature. Set the threshold temperature value (example 75 degrees) and use if loop. Inside the loop will be the code for motor and LED.

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
