Sneak peak during exhibition

[junjunfinale]

Thankfully, it is a SUCCESS!

Thank you everyone throughout this journey!

Sweii, your guidance and understanding to me. Whenever I need help, you won't hesitate to spare some time with me. When my anxiety got worse during January, i really thought I couldn't make it, but you gave me so much support that I needed.

Lin Yew, thank you so much for guiding me step by step. I know I might be blur at times, but you made sure I understand. To me is an achievement unlocked to actually learn so much from you! Now I know, that every detail counts in making a great work!

Ron, thanks so much for giving me so much insights and giving me tips on how to solve problems when I encountered them. I learnt and grew from them. Also, thanks for the advice too, the word novelty, helps a lot in finding something much more than what it seems.

Louise, thank you sincerely. For those words of advice when I was doubting myself, doubting my abilities, doubting my work. Thanks for helping me realise the value in my work, and most importantly, the value in myself as a designer. I will always remember to keep my humane for my design in future, and not take it in a negative way.

And my fellow classmates, thank you for always being there. Whenever one of us are down, we would sit or stand in a circle together and comfort each other. You guys gave so much strength in me and how I wish our friendship bond would last forever, and I trust it will actually... I wish all of you success in your future endeavor and if you need someone, I'm always here.

I observed the first day of exhibition and made some amendments.

People still won't walk into the installation as the entrance obstruct them, so I discarded it.

The enter word is unreadable, so I change it

People don't know what is the distance to initiate the motor, so I added white dots, same size as the base of the stand, as indication.

Finishing and setting up (my small workplace haha)

[junjunfinale]

I changed the connector for the box to the pipe. And ron suggested the sensor should put there in order to hide it better.

First few failed due to my mistake in measurements

Then I finally succeeded, but... the plate was dislocated... thus the results

A note lin yew left for me hahah

Digispark configuration

[junjunfinale]

Digispark Configuration

Previously I succeeded in using digispark as it was already opened by someone. But when it comes to new ones, there are issues.

First my system need to download the digispark system into the arduino.

Link given: https://www.instructables.com/id/Digispark-Attiny-85-With-Arduino-IDE/

Then test with the blink code. Upload it then unplug and plug it back. If it blinks means the device can remember the code. Unfortunately, none remembers the code... So I need to do some configuration

And with the help of my friend Eric, finally it could work!

Digispark X Ultrasonic Sensor

I tried digispark during my experiment stage on gear. It works well, the code can be uploaded. It has limited memory, so only the servo library (that is already available for servo called SimpleServo) can be put in, Adafruit LED library can’t... 

https://digistump.com/board/index.php?topic=1157.0

Ultrasonic sensor has only been used in arduino, so I didn’t realise that would be issue if use digispark, which now it happens! So I find solution online, there are a few sites I visited:

https://www.arduinolibraries.info/libraries/hcsr04

https://www.arduinolibraries.info/libraries/ultrasonic

https://hackaday.io/project/13122/logs

https://runtimeprojects.com/2016/04/arduino-ultrasonic-range-finder-sr04/

https://arduino.stackexchange.com/questions/60292/digispark-attiny85-ultrasonic-sensor-input-problem

https://forum.arduino.cc/index.php?topic=601193.0

https://www.instructables.com/id/Ultrasonic-Range-Finder-with-an-ATtiny85/

Then I found this success one on YouTube:

which brings me to his blog and resources:

http://projectsfromtech.blogspot.com/2013/04/newping-library-on-attiny.html

But I give it a try, install NewPing library, yet it couldn’t work... I searched on Arduino library that is available for this sensor, but it feels that NewPing is the most reliable one.

Then I asked Ron about it, he told me the digispark couldn’t work with serial. I need to translate the serial into cm (which is already done thanks to the resource code). He added that I need to DISCARD anything that associate with serial (eg serial println, etc.) And you know what? IT WORKSSSS!!!

Assemble time

[junjunfinale]

Cement finally dries after 2 days! I add a cap to make sure the cement won't break

[junjunfinale]

So I decided to remain using plastic pipes

[junjunfinale]

Cement time!

Video of it

Finally I succeeded and made 3! For industry guests coming to test it out...

Of course it wasn't as smooth... like one of my motor got short circuit due to a broken breadboard... but luckily at the end all seems well

[junjunfinale]

Of all suggestions, I remained the slider one as I did it before. But the first ones failed as I did wrong calculation
