Day 2
On day 2 lab was to build an LED circuit and get it to function like the K.I.T.T. car from the Knight Rider TV series. The materials used are; breadboard, 4 resistors, 6 wires, 4 LED's, an arduino, and a computer.
This is the arduino used from day 1 that will be used to program our circuit.
The C syntax for calculating energy of an object in motion through a ramp.
The C syntax for centripetal acceleration, potential energy, and change in potential energy from left to right.
The completed LED circuit. Here the red wire is the one that is responsible for bringing in power to the circuit, also is the grounded wire, and the resistors are there so that the circuit doesn't have too much current running through it, which could destroy the circuit board.
Practicing increment and decrement operators.
Practicing the printf command to return a value of printable characters.
Exercise to determine the height of a person using forensics based on their femur or humerus heights.
The circuit here was programmed to turn on from the red light to the yellow light and come back to red, to mimic the K.I.T.T car's effect.
Blue light next in series.
Green light actuates after the blue light.
Yellow light activates last in the series, where it will then go back to the red light.
K.I.T.T. Car from the Knight Rider.
