Joanne Ma. Professor Kimiko Ryokai, Info C262, Fall 2021 Description To understand rotational and linear motions, we were tasked with using a servor motor as an ouput to make an object crawl. Materials Arduino Breadboard Wires Resistors Potentiometer Servo motor Graph paper Clothing tag Masking tape Part 1 — The Servo Motor Control the Servo through Serial Monitor I connected the servo motor to…

Alex Gao, Joanne Ma, Jessie Mindel, Julia Wang, Clarissa Wu. Professor Kimiko Ryokai. INFO C262, Fall 2021 Summary We propose kǔkǒu box (苦口), an interactive and slow technology that allows people to periodically re-experience the accumulated emotions and semantics of their past words through the taste of chocolate. Once a week…

Joanne Ma. Professor Ryokai. INFO C262, Fall 2021 Description This week, we used DC motors as an actuating device, where DC motors convert direct current into rotational motion. We also learned to use a diode in the circuit to protect the transistor from spikes that are created by motors as they…

Joanne Ma. Professor Kimiko Ryokai. INFO C262, Fall 2021 Description This week’s lab was about using capacitive sensors to measure touch proximity. How this works is that the longer it takes for a capacitor to charge, closer someone is to the sensor. I was excited to test out different items to…

Joanne Ma. Professor Kimiko Ryokai. INFO C262, Fall 2021 Description This week’s lab takes what we’ve been learning about pulse width modulation (PWM) from the beginning of the semester, building circuits with Arduino and different I/O to make some more noisy design artifacts. We used the piezo buzzer and tone() function…

Joanne Ma. Professor Kimiko Ryokai. Info C262, Fall 2021 Description I was really looking forward to working on this week’s lab because I’ve been wanting to learn how to use a force sensor for a potential final project application (or just a fun chaotic project where force is applied to a…

Description — This week’s lab had us explore analog inputs with potentiometers. Zeke was super helpful during office hours in helping explain how the potentiometers, resistors, and LEDs work together as a circuit. Potentiometers act somewhat like a resistor, but allows for more user inputted through twisting the knob, which controls the…

Team: Vivian Omondi, Julia Wang, Jessie Mindel, Alex Keming Gao, Oscar Chan, Joanne Ma, Benal Johnson, Akash Mahajan Description We observed that our collection of thoughtless acts were of objects that were re-purposed to hold something that designers did not intentionally create affordances for in the objects’ original design. …

Joanne Ma. Professor Kimiko Ryokai. INFO C262 Fall 2021 Description The goal of this lab was to apply what we learned about pulsewidth modulation (PWM), an analog input, to “dimming” our LEDs. PWM is all about varying the width of on/off within a cycle. Since microcontrollers like Arduino can only…
