This instructable was made as part of the CS graduate course “Tangible Interactive Computing” at the University of Maryland, College Park taught by Professor Jon Froehlich. The course focused on exploring the materiality of interactive computing and, in the words of MIT Professor Hiroshii Ishii, sought to “seamlessly couple the dual worlds of bits and […]

High Level Description: For part 3 of the lab, our group decided to build a “Simon” game. Our game setup uses 3 buttons and 4 LEDs. Each button corresponds to one LED and the 4th LED is used to indicate an error. The game starts with the Arduino flashing one of the 3 lights, chosen […]

In the realm of do-it-yourself (DIY) electronics and robotics projects, Arduino stands as a prominent open-source microcontroller platform. It boasts a user-friendly nature and enjoys a vast community of users who actively contribute their projects and provide assistance to fellow enthusiasts. Throughout the year 2022, we embarked on numerous remarkable ventures involving Arduino, ESPs (such […]

While the field of robotics is continuously expanding at a remarkable rate and better performing robots are created every year, robotics still remains out of reach for many students and researchers. The main reasons for this difficulty are the high complexity of the hardware and software of robots, and their typically high cost. We believe […]

This is a project to monitor the number of birds that visit my bird feeder, as well as record the amount of time spent feeding. I used an Arduino Yún and a capacitive touch sensor, Adafruit CAP1188, to detect and record the birds feeding. On a routine basis, the accumulated data is sent to a […]

Introduction   Our project, in one sentence, is an orientation independent 3D LED display. We were inspired by various videos on youtube of similar cubes but also by the idea of creating an interactive 3-dimensional display. We built a 5x5x5 LED cube display and controller board which interfaced the cube to a Mega32 microcontroller. We […]

My partner and I wanted to make heart rate monitor that does more than simply measure a user’s heart rate. Our heart rate monitor talks! Each button gives a verbal description of its functionality and makes the measurements visible on the screen. This monitor will save the last four readings, display them, average them, and […]

Readings in Physical Computing Ch 6. pgs 87-136 (this week and next week) Ch 7: Serial Communication [137-143; 149-150; 153-161] Before the lab You should have already successfully installed the Arduino environment on your laptop, built the LED circuit, and successfully load/run the “blink” program to make the LED blink. Congratulations! In lab exercise Objective In […]

Here at Mikamai, we often organise events and hackathons. After the last hackathon, someone left an old doll, and it was kinda creepy… so why not make it even creepier? I decided to put two red LEDs instead of the eyes, and a vibration sensor to turn on the LEDs when you shake the doll. […]
