Arduino communicates with Maxmsp

Getting Arduino to communicate with Maxmsp should not be too difficult. I was lucky enough to make it work with this max patch ' Arduino2max', written specially for what i need most in my project.

You may read more about Arduino2max and download it here.

I still have one big problem here.

After the first test out which was successful ( as shown in the below video) , it is not working anymore until now. (that's why I said I was lucky)

working on it right now. hoping to get it fixed as soon as possible.

*May luck be with me!*

is checking out more about Maxuino, different versions of Arduino IDE ( maybe the updated version doesn't work in this case) and Pure data + arduino , etc relevant stuff.

ps: Thank you Cheesehed!

My sensor works!

was trying out if my PIR sensor is working.

TARA!!!!

It works! and i got the codes from here. I realized that this sensor ( Parallax PIR sensor : which is considered as a branded sensor according to the guy from Jalan Pasar) works really well. I mean it is quite sensitive to detect motion but when motion is too fast, sometimes you will have to slow down your motion. example like if you wave your hands too fast over the hot zone, i think the sensor can't really detect something moving over it.

was Happy and excited and to have some progression. This is done i think 3 weeks ago. :)

From the serial monitor in Arduino IDE, this is what we see.

Arduino tutorial

one of the tutorials I've done with Arduino and potentiometer.

the potentiometer controls the speed of the LED lights running.

just to share. :)

Sound Recorder

One of the most important elements in my project is the sound of water. In order to get clear and high quality sound. I went around doing field recording on actual spots of water source. Tools that I have been using to record the sound of water is the portable sound recorder shown as below.

Firstly I used the

Zoom H2.

I find it easy to use and it's handy and light. very convenient for me to bring along in my bag.

image source.

Then i tried the slightly advanced version of the same brand. It has more features and has two input and more feature; slightly bulky but it is still fine to be carried around.

Zoom H4

Other experiment:

**playing with the piezo vibration sensor which is made into a hydrophone; looks like this.

The hydrophone is connected to the sound recorder, eventually I got clearer sound of water with all the extra noise filtered out. because it is made of piezo vibration sensor which only detects vibration, that is why in the output sound the noise are gone.

PIR sensor

Image source.

PIR stands for Passive InfraRed and this motion detector is what I will be using in my project.

It scans and searches for passive IR reflections (such as a human). Basically works like an on / off switch ( I/0 ).

What I will do is to set this detector with my Arduino set, and try it out with the code from Arduino playground.

DFRduino Duemilanove 328 ; with USB connection ;

100% Arduino compatible.

VPT tool test out

VPT: Video Projection Tool

It is a free software where you can download it from here.

This is an application for projection mapping which I found suitable for my installation set up.

Screenshots of my test out.

The very first thing i got from the output.

Then, still confused.

got the mapping!

arranging the videos.

smile :)

*Thank you Khairul Johari for sharing this application in the class. ^^

It is not very difficult to use. first you need to read the vpt manual to have a basic understanding of the interface.
