I have made some progress towards the ATP synthase model (the top half anyway), and am discussing the mechanisms with the incredibly helpful technician at the Institute of Making. To this end, I have learnt how to use SketchUp, and have made a model of how I would like to put together the parts of the ATP synthase.
Of course, first drafts are not normally last drafts, so I am still working on it…
I confess I am a complete n00b when it comes to arduinos. I am also totally paranoid about breaking things. But because Charmian encouraged me to “just give it a go” during Friday’s tinker session, I finally had a bit of a play this weekend.
To begin with, I simply loaded some of the basic example code that comes with the arduino software. Soon I went on to recreate a couple of code examples I found out there on the world wide wobble. Here are the results:
Here is a bit of random music courtesy of the code and instructions provided by Super Awesome Sylvia:
I used a piezo for input instead of just fumbling with the board itself as the tutorial suggests. Not exactly Mozart, but at least nothing blew up or melted down. 😉
I also managed to replicate an Instructables tutorial for a mood light:
All in all a productive weekend.
I want to see if I can get the MakeyMakey to use the light sensor from the Arduino start up kit – it might be a better way of tracking someone’s cycling speed. But I initially struggled just to get the Arduino not to just switch it on all the time. I now understand what was said in the last meeting about the resistance being too low! It didn’t make sense to me before.
I was hoping that I could connect the headers on the MakeyMakey to the headers on the Arduino, so it could connect the circuit when the Arduino program told it to. But simply connecting it would just switch it on, even when I told the pin digitalWrite(mPin, LOW), or whatever. Just being connected to an output pin was enough to switch it on.
Turns out, instead of switching pins on or off, you can switch them from INPUT mode to OUTPUT mode, to switch it off/on instead. I know you guys are all more experienced with electronics than me, and can probably see a million easier ways of doing this, but I was happy to have implemented what I have learnt so far and solved a problem in my own way. The reason why I am doing this is because I understand how to get the Makey Makey to talk to Flash, but the tutorial on Arduino and Flash is beyond me – if anyone knows how to do that, I would really appreciate some guidance.
I have to say, connecting up wires on that breadboard is kind of addictive…
I’ve only tried this out with the button, but I know how to do the light sensor circuit too, so I think I can put those two things together…
In the interest of having something to show for my efforts at the end of the summer, I am going to see if I can do the zombie-chasing game. To make the work out more intense, I think I’d like to give the bike rider the ability to fly over the zombies if they pedal standing up. That would be so cool…
I am also working on figuring out the Arduino – I was this close to making a ‘night light’ – but got stuck on a breadboarding issue. So I am pausing on the Arduino videos to learn more about bread boards. If anyone knows any good sites for this, it would be much appreciated!
