Write an arduino sketch that programs your multi-colored led so that the red and green leds are on for 500 ms, then only the blue led is on for 500 ms, then finally only the green led is on for 500 ms. this pattern of leds flashing should continue forever. circuit hint: • you can wire up leds from digital pins 10, 11, and 12 of your arduino with a 330 ohm resistor for each led. make sure that all the grounds are connected together to arduino gnd.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
