Hi Justin,
There sems to be a bit of confusion about the tutorial blogging.
Are we meant to do ONE blog for each tutorial that shows our progress through the task (with the tag you ask us to use), containing images, text, an upload of the sketch, etc, possibly video, and do we edit this as we go through the week; OR should we regularly document via several blog posts our frustrations or otherwise as we construct each sketch.

The blog may get pretty busy!

I think it would be best to use a single blog post per tutorial.

Hi, Justin
I'm new to programming.
Could you upload your tutorial slides yesterday?
I have to learn more about coding from the slides.

Hi Justin,
Have blogged most of my homework - having trouble with the video uploader, so have just placed linkis in the blog to the relevant videos.

Hi Justin, Could you upload the note of last tutorial? i got lost in the last tutrial. i didn't learn physics in my high school here. i had the basic knowledge of the electrics, but in Chinese version. i tried to catch up now.

Hi Justin,

I've been working on an extended version of tute 1. Just before the tute was over I asked you about connecting analogue input to the Arduino board. I swear I had it figured out, but when I came to implementing it, alas, it isn't working! T_T

I thought I'd blog about it (here) to give a bit of detail as to how I approached it. Any ideas as to why it isn't working?

Thanks

Hey Stephie,
See my comment on your blog post. Ground doesn;t appear to be connected form your breadboard to the Arduino ground.

Hi Justin,
not sure what the tag(s) are meant to be for Tutorial 2, so I have used tutorial _2.

HI David,

All that is required assessment-wise is a single blog posting documenting the completed tutorial exercise. This is the blog posting that should have the special tag. (Which I didn't provide last time; D'oh.)

If you want to blog about the trials and tribulations, then that's fine too. :)

hi Justin, this is Kerry doing the TREE layers thing responding to saving shower water. i have some questions about the PUMP. because i want the Pump to contorl the liquid level in 5 different layers, does one pump can contol many things?

you suggested me to use the Pump insdie the printer. if my TREE layer is samll (around 10 cm height), is it really hard to adjust the liquid level by the Servo motor? i want the real time liquid bar to present the water waste. do you think the biger size thing is easier to contorl?

i have more questions about the technical things. may i talk to you in the tutorial ? i want to show you the detail structure of my design.

Hi Justin,

In our last class I asked about infra red transmitters and detectors. I have a detector that has a centre frequency of around 38kHz, and you indicated I could modulate the transmitter using delayMicroseconds. This works to a limited extent, but as soon as I add any more code to my sketch, the delay changes and therefore the receiver no longer works. Have you used this before, or do I now need to build an oscillator for my IR transmitter...

Hi Justin,
please disregard my previous posting, as I have found an example of a sketch that makes the system work. It doesn;t rely on the loop(), but does a short burst in a for loop then immediately checks the detector.
