Cristal Light : LED Module#
Goals#
The module for a LED / Cristal is to change the sense of the light.
LED in circuits are very important to find how it work, how it doesn’t work. I use it to put on the circuit when I turn on the interrupter. Then I know that the device it’s working with my 4V battery or 2X 3.7V cell coin.
The LED has a utility to kwneledge, to communicate with the circuit. The position of the LEF is udge in the device, for us, human…
The cristal to refract the light. The cristal can be a shell, or an anti-shell. It’s a fragile part of the circuit, but also the cristal says to us that we need to take care about our electronical devices. They are material from the earth. All our world turn around the industry and the process of fagricating with the progress…

Resistive material#
Velostat is use to be a pressure sensor as a piezoresitive material material. A potentiometer is a variable resistor value. The variable value of the resistor can be constantly or with differents step. I have decided to use it in order to make a potentiometer.

The quality of this product seduced me to make a module like a swith or a button to change one thing in the circuit if I had an Attyni or a micro controler for the frequency for exemple.
