'''ASSIGNMENT II - CONCEPTUAL SENSOR ''' | |||
---- | |||
[[File: Sensor.jpg]] | |||
On this one I was instructed to open the pin 6 and 7 on Astable Mode in 555Timer and play with, plus that with a serie of 555Timer Circuit we are able to modulate the sounds better. | |||
So I worked on my circuit and have decided to work with 3 555Timers connected. The first circuit was used light sensors and the second was used graffiti on a paper as a sensor table. | |||
[[File: Paper.jpg]] | |||
On the first circuit from the pin 6 was opened 2 channel where different resistors was connected with the LDR and after connected with pin 7. | |||
[[File: Circuit4.jpg]] | |||
On the second circuit, was opened 3 channels where each one also had a different resistor value connected with the paper. | |||
[[File: Circuito.jpg]] | |||
The values are: | |||
The result is that the variations of sound was even greater than the expected cause now it was able to work with 5 variables. | |||

'''FINAL PROJECT - The Sounds Of Changes ''' | |||
---- | |||
[[File: Articulando.jpg]] | |||
Experimenting more with the 555Timer, it was realised that if is opened the pin 8 besides the pins 6 and 7 , it also was possible play sounds frequencies. | |||
So, as on the preview experiences I opened again channels at pins 6 and in 7 but now with 4 resistors in it. | |||
To make some fun i opened also 3 channels at pin 8 but connecting with different values capacitors. On the picture yellow tape represents pin 8, and green and blue pint 6 and 7 respectively. | |||
[[File: fabric.jpg]] | |||
It was stitched lines of conductive yarn on the fabric and at each line has a resistor or a capacitor. | |||
Thus, each line connects with one of those 3 wires that was sewed in a strip fabric which were plugging one of the pins. | |||
