Lab exercise --analog inputs --using potenciometer:
Lab exercise --analog inputs --using FSR 1
Lab exercise --analog inputs --using FSR 2 -- creating delay btw both pair of led´s
Assignment: Luv-o-meter
I love the idea of creating a luv meter but ideas are not passing by my head in this moment so I decided to face this assignment as an exercise.
The idea I have is to create a kind of wearable - a pair of gloves - that a couple can wear. In each glove there is a heart (made of led´s) and a force sensor resistor.
When the couple grabs their hands the heart will light up!
The idea doesn’t work as a luv-meter, it’s just a physical representation of the gesture of being together.
For the purpose of this exercise and because I’m using a FSR I want to work and explore the possibilities of this kind of variable resistor. So if they grab hands stronger they will light up the led´s in a certain way.
This doesn’t mean that I want measure love with force or pressure. That is not my concept of love..so it’s just an exercise.
Another thing that I figure it out, when exploring the possibilities of the FSR, in the breadboard, is that, this is not the right sensor to use in this particular situation.
The FSR is very sensitive and this one that I borrow from a 2-year student (thanks, eric) is big. I saw one smaller on the Sensor workshop page, maybe this work better for this purpose. But I think it will work better if it is attached to a fixed position and not a glove -- our hand is always moving around!!
" I tested force and resistance characteristic with 10ohm, 1Kohm and 100Kohm resistors. First, I put from low number of resistor (10ohm) to high number of resistor (100Kohm). If I used 10ohm, a decrease in resistance was slow and needed more force. On the contrary, If I used 100Kohm, a decrease in resistance was fast and required less force."
Let’s try this!!
1. Heart -- 10 led´s ( 5 output´s == one input for 2 led´s in series)
2. Gloves -- the idea is to use conductive thread to connect led´s, maybe later explore this feature
3. Get more control of the FSR -- how attach the sensor to the glove?
