Jacob sullivan and Antonio Raynore skill review

For this project we explain in the video that our concept is to coat ground soil with certain bacteria that grows under different temperature conditions. In this way if it is cold out side maybe a bacteria that grows blue flourishes and when the soil is warm a separate bacteria that grows red will flourish. It would then be possible to glace out and see what temp the soil is.


For the Prototype experience we went with the theme DIYbio and have utilized capacitive sensing, thermochromic actuation skill in this experience. We are simply trying to show what it might look like to have the “soil” change colors based on temperature



Jacob’s capSense pear led

My video

I kept it very simple and used a pear as my organic material to trigger the led.

Here is my code

#include <CapacitiveSensor.h>
CapacitiveSensor   cs_4_8 = CapacitiveSensor(4,8); // 1M resistor between pins 4 & 8, pin 8 is sensor pin, add a wire and or foil
void setup()
   cs_4_8.set_CS_AutocaL_Millis(0xFFFFFFFF);// turn off autocalibrate on channel 1 – just as an example
void loop()
 long sensor1 =  cs_4_8.capacitiveSensor(50);
    Serial.println(sensor1);  // print sensor output
   if(sensor1 >= 1000)

Jake Sully’s Hand Crafted Analog Sensor

The first idea I had for this project was a salt water mixture that I could add more salt to decrease the resistance. A few failed attempts later and I shifted gears to a slide sensor. I first took Conductive tape and connected those in a series so that I could slide one taped surface against the other. Due to how well the conductive tape conducts I was not able to vary the resistance by sliding away from the contact point. It was suggested to try conductive yarn so I used a combination of yarn and tape.


Sullivan’s Soft Switch

16176270_10154271075278034_2055020857_nFor this project I kept it simple by using the blink code provided in the Arduino library.

I choose to do the paper circuit reading assignment, as a result I combined the reading assignment with this switch assignment. I used conductive tape as my switch and created paper clip and alligator clip wires to attach
