Week #8: Make-through

Describe your previous experience with Raspberry Pi: is this your first time using that board? How is it different from Arduino or the AVR microcontroller Family?

Describe which input and action components did you chose for your assignment: is your input analog or digital? Does your action component require an external power source? How did you handle that? How did you wire the components with the Raspberry Pi and which pins did you use?

Describe how you programmed the Raspberry Pi using Python Programming Language: which functions did you use? How are the python commands or functions similar or different from Arduino C syntax?

Describe problems you encountered as they happened throughout the process. How did you solve them?

Make sure to Use screenshot images and videos to document the process

OBJECTIVE #1:

Describe my previous experience with Raspberry Pi: is this your first time using that board? How is it different from Arduino or the AVR microcontroller Family?

Unsuccessful(trial): That I didn't how can I make table (to show the deafferents between Arduino and Raspberry Pi) in the week, so that I made in word and take photo.

OBJECTIVE #2: Describe which input and action components did you chose for your assignment: is your input analog or digital? Does your action component require an external power source? How did you handle that? How did you wire the components with the Raspberry Pi and which pins did you use?

Trial #1 (successful):

Input Motion sensor PIR sensor and action taken by led.

Input: Signal from sensor as result of detection

Output: Led is on and print sentence There is motion or no motion when detection and not detection.

Power source: Using the power 5v from raspberry PI.

Component: raspberry, led, resistance 330ohm, and PIR.

Library used : Time (import timed) and RPi.GPIO as GPIO (import RPi.GPIO as GPIO)

Pin used and connection : GPIO (BCM) pin 23 as input (from sensor to raspberry PI) and 11 as output (from raspberry to led) see the following figure.

OBJECTIVE #3: Coding and Testing (still working on it)

Describe how you programmed the Raspberry Pi using Python Programming Language: which functions did you use? How are the python commands or functions similar or different from Arduino C syntax?

Trial #2 (Successful): A glimmer of hope

some explanation of main key words use in code (with blue font)

import time// import library of measuring time

import RPi.GPIO as GPIO // import library of control of GPIO in Raspberry pI

GPIO.setmode(GPIO.BOARD)// to activate the all GPIO pins

GPIO.setup( 11 , GPIO.OUT)// Define the pin as input or output

while True: // repeat the line under this sentance to infinity

GPIO.output(11,0) // volt( pin-11)=0

time.sleep(1)// wait one sec

In real, I found the Python language is more easy as Arduino C/C++ , it can be as result of many practice I did in python.

Codes files and some explanation

Video of testing

Problem: confused when dealing with the pins of the raspberry pi ( Board and BCM )

Potential Solution: Dealing with Photos pin out of raspberry and try to print the photo to be more easy and don't make mistake.

CONCLUSION

What I learned this week is...

I learnt to deal with first time with raspberry Pi
Learning the language (python)
