The to detect even with a 1 second delay.

The purpose of this experiment is to enlighten students on
how to properly become familiar with the Arduino micro-controller and its
functions. This lab specifically shows and demonstrates how to enable the
Arduino micro-controller to control an internal with a bit of physical wiring and
external LED by writing, downloading, and running the program onto the Arduino
chip. Another aspect of the program is to illustrate the precise speed and
assess the delay function, which is used to change and define the time interval
of the delay when the loop is being executed justifiably in Arduino. This lab
consists of four parts each with its own task. The first part of the experiment
is to write a simple program that can control the Arduino’s internal LED,
causing it to blink at about 500 milliseconds or roughly half a second. This is
simply achieved by using the delay function, to make sure it works and records
the blinking time as it should exactly. The second part allows the group to use the written program
from part one to blink an external LED through a resistor I/O pin 5 of the
Arduino, using the same delay functions. We then use the oscilloscope to help
draw a trace that is measured and recorded across the LED and resistor to
receive the pulses while looping an in a cycle for the program. For the third
part of the experiment the code given to us in the lab is then utilized for the
external LED to blink only three times. Those subsequent waveform of the pulses
can only be determined by using the same oscilloscope. The pulses in the output
waveform must be examined through the oscilloscope in the third part due to the
three blinks or flickers of the LED are happening so quick for even the human
eye to detect even with a 1 second delay. Finally, the fourth part is to change
the execution of the loop for the different values of Arduino delays given
which were 1ms,5ms,10ms,20ms,50ms,100ms, and 200ms verses the pulse width which
is measured and recorded from the oscilloscope and plotted in Excel. Overall, I
feel our group achieve the objective of the experiment by effectively implementing the
given programs and improving upon the code differently with the same circuit
