Physical Computing – Lesson#2
For the second lesson of P.Comp I kept on practicing and investigating everything covered both in class and in the labs. By drawing ideas, trying them and failing every other time, I tried assembling different combinations of LED’s using resistors, switches, potentiometer, slider (fader) and even an attempt of using a transistor & light sensor.
- Basic LED Board:
I started out by just making a very simple and straightforward led circuit using a 220Ω resistor, powered by +5V from the Arduino R3 board.
- LED & Button Switch:
As this week’s assignment involved using switches I took some time to investigate some of the logic behind switches and made a very simple button switch that turns on an LED while pressed. Around this point I also started working with external power supplies in the shop, which was frightening at first (a big white block on my table?) but ended up being very easy and convenient to work with.
- LED & Potentiometer:
After building a simple button switch I moved on to experimenting with potentiometers and sliders, and made a LED controlled by both a Bourne B203 potentiometer, and a Phidgets N1112 slider.
To sum this week up in a visual manner, here is a compilation of different circuits I tested and learned throughout the week
