what I used for this project is RTC, LED Matrix, two shift registers, capacitor, magnets, LED, conductive tape.

I combined with Pcomp and soft circuit so user can play with each clock and make own shape with cubes.

Each clock shows different time of location and weather.

From this final project, I have worked with pulse sensor and it was first time to make a interaction project.

It was really fun and what I learned from this project, as people are trapped in technology,

I want to provide people an opportunity for themselves to interact with hear rate which they can’t see.

Based on critique, next step is show different way with pulse sensor and add more personalized visualization.

I tired to upload in github but I dont know why It is not working.

so I post on google documents.

this is my link.

processing code

so this time, I tried to finsih countdown code and save frame from video camera.

this is video

this is my processing code

I used AN with range finder. first I checked sensor value and divide by 4 drawing.

Each one draws different shape.

We made a small “Rube Goldberg Machine” using a toy bug as an input, a photo cell as a sensor, a servo motor as an actuator. We also adopted a ball, a balloon and a needle for this device.

Julie & Nori

We used a pulse sensor Julie bought at Maker Fair. Pulse sensor consists of  a led and a photocell as a detector. You can see how a pulse sensor works from this site.
We applied these sample codes. We downloaded “P_PulseSensor_06.zip” and PulseSensorAmpd_Arduino_01.zip .

While I was working on this, I almost gave up but i tried to connect again from the first part.

I am so happy that this project is exactly what I want to do at the first time.

I used 8×8 dot matrix to show emoticon.

there are 3 option (I used random function) led1, led2, and led3.

Once it start I used buttonPin which is pin7. if this button state is high, it generate random number (0 to 2)

this is my code.

Parallel Circuit

Series Circuit

Parallel+Series circuit

Schematics + Calculations

If I calculate with LED resistor,

every LED has resistor and my LED resistor is 3V so

1. Current of first parallel circuit will be

5v-3v=2v

I=V/R

I=2v/100ohm

20mA+20mA+20mA=60mA

2. current of second series circuit will be 20mA.

3. current of third parallel and series circuit will be

I=20mA

I2=10mA

I3=10mA

I am taking Physical Computing so it was not really new and it is fun. From Pcom class everyone is good at arduino and the progress of class is fast

so I had hardtime to catch up. I think this cclab with arduino will really helpful to understand circuit.

Also I haven’t calculated ohm’s law before so it makes me to understand more about resistor voltage and current.
