This week I spent some time exploring two different methods of synchronous serial communication: I2C and SPI. Since I didn’t have the specific modules in the class labs I made use of two modules that I did have including an SPI RFID Tag Reader and an I2C OLED 128×64 Pixel Display. I have wanted to […]
This week in Programming A to Z we learned about Markov Chains as a method for generating new text based on a source text. Named after Adrey Markov, Markov Chains are a mathematical system to navigate between different “states” based on a probability table. On a granular level these tables show the number of times […]
In this lab I combined a number of capabilities to create a pointing and selecting device (mouse) that uses two-way (duplex) communication. Here is the circuit I used along with a Fritzing diagram: Code with some smoothing to the readings: Taking a look at the X and Y axis IMU readings in the serial plotter […]
Building on what I learned in the last lab about serial input from Arduino to a computer running P5.js, this lab was about reversing the direction and outputting serial data from P5.js to an Arduino. The goal of this lab was to feed input from mouse clicks on the canvas of a P5.js sketch out […]
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 […]
Coming up with an idea for a bot is easy! Choosing one to make is hard. I pitched a dozen concepts to friends and family before setting on one that felt right. After much hemming and hawing hearing my husband mention his co-worker Adream triggered it. A dream! That was it! I have always had […]
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 […]
This week for Programming A to Z I made an attempt at creating a word counting algorithm. Coming off of the first round of (Presidential)? debates I was feeling inspired to do some word counting to determine what words were most commonly said by each of the speakers. The transcript I was able to locate […]
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 […]
