Transistor Lab

Very last minute, I’ve gotten to the transistor lab while stuck working on my final project.

physical computing

Serial conenction

Hooked up the arduino to the mac via USB and using Processing to show a visual reference to the connection which I’m manipulating via the potentiometer.

Servo and Tone

I think I’ve just made my own Theremin Machine. Or at least something to annoy the neighbors.

Under pressure

Named after that song from Queen, now I have to program the arduino to recognize an analog input. Meaning, it’s not just as simply flipping a switch. This requires and entirely different mindset.


Using a knobthingy commonly known as a “potentiometer”, it allows the light to switch on once you turn it past a certain point. Notice that the potentiometer does not use a resistor and is an exception to the rule.

Now I wanted to control the intensity of the LED using a light sensor. So I ended up with this. It still needs a bit of tweaking on the range the sensor recognizes but it more or less captures the desired result.

I’m still working on two LEDs and two pressure sensors.
