Hi, i want to make this: http://www.instructables.com/id/DIY-Force-Sensitive-Resistor-FSR/?ALLSTEPS
I want to use it with sound frequencies that come out of a 555 timer. However, I want the sound to be normally off, and the harder i press the force sensor, the lower the resistance I get, therefore the louder the noise/ higher the pitch. How would I invert the resistance?
