Projects for the ITP course Introduction to Physical Computing
For this lab I setup an interface between an Arduino Nano 33 IoT, reading analog values from a potentiometer, and a P5.js sketch. Typically web browsers do not interface with serial ports on a computer so I had to use some additional software including the P5.serialport library and the P5.serialcontrol app by Shawn Van Every (updated by Jiwon Shin). […]
In this lab I took a closer look at asynchronous serial communication between an Arduino and a computer. This type of digital communication makes use of serial transmit (TX) and receive (RX) over IO ports to communicate at a set data rate. The lab demonstrated that there are a number of ways for an Arduino […]
This week Mai and I made some great progress on our musical Dodecahedron. Feeling pretty confident about the circuit on the breadboard we moved to a more compact arrangement on a soldered board. We met in person on the floor at ITP to make a second Dodeca so we could both have one at home […]
Over the last week I had the pleasure of getting to know my classmate Mai. From our initial video call we brainstormed ideas for our first project in Physical Computing. Mai expressed interest in creating something musical but expressed concern that she didn’t have much of a background in music theory. I happened to have […]
For this lab I set out to control a servo motor based on input from a force sensing resistor. Going into this I had some concerns about the ability of the Nano 33 IoT to supply the necessary voltage and current to power the FS5106B servo motor I had access to. Initially powering the servo […]
For this lab I created a few different circuits to generate tones using the Arduino Nano 33 IoT. The first circuit below made use of two touch sensors connected to an analog input, with one sensor connected LOW to ground and the other HIGH to 3.3 volts. Next I tested reading values with the following […]
In this lab I created two different circuits making use of analog inputs on the Arduino. Analog inputs are able to read a range of voltage inputs from zero to the voltage of the board which in the case of the Arduino Nano 33 IoT is 3.3 volts. The goal of my first circuit was […]
This week I went hands on with an Arduino Nano 33 IoT and setup circuits with logic running through the Arduino. For this first lab I made use of digital IO (inputs and outputs) which are capable of reading the values on and off. The idea for this lab was to control an LED turning […]
In this lab I reviewed different types of switches and their terminology. In addition to using switches in a few different breadboard circuits I also created a switch of my own! For my first circuit I created my own switch. Looking at what I had on hand I decided to repurpose some cardboard packaging, copper […]
In this lab I reviewed the basic functions of a multi-meter then created a few circuits using LEDs, resistors, buttons and a potentiometer. Making my way through the settings on the multimeter I started with the diode continuity function. Holding the multimeter probes apart my multimeter read “OPEn” indicating that the circuit is open and […]
