This week has been, at the end, my first Interactive Exhibit Design class. From the first moment, and working in pairs, we were given an Arduino UNO device, with the corresponding trainer, wires, light-emitting diodes (aka LED), light sensors, one button and the USB cable to connect to the laptop. I cannot say I weren’t excited. I’ve been hearing about Arduino almost 4 years and finally yesterday I could use it.
As a guy with some Computer Sciences Old School background, has been amazing to see the simplicity of Arduino and the magic of the in board microcontroller. I remember the times when I had to pay a lot of attention in order to get my circuit working. If you made a mistake, you should rethink about your wiring, connect the oscilloscope and analyze what the hell was going on. Now, with Arduino, you can layout the components of the circuit and build as much programs on it as you want. For me, it is like magic.
This first contact was näive. My classmate and I made the tipical first experiment: make a LED to bright. After that, and using the software development kit also provided, and based on Processing, we plug a light sensor, some resistances and build this time a proximity alarm: if you bring your hand closer to the light sensor, this one lose some light, then our code was design to make blink a diode in a inverse way to the light the sensor were receiving. Really funny and didactic.
So now, I am exciting again for the next class and to see what Arduino has for us!
