On this one I was | 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. | So I worked on my circuit and have decided to work with 3 555Timers connected.

'''FINAL PROJECT - The Sounds Of Changes ''' | |||

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. | |||

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. | |||

Inside a bag was set up the circuit and out side the speaker. | |||
