[imsolidstate] built his own pressure ... sensors. As the foam gets compressed, the capacitance between the two pieces of copper changes, a measurement that is fairly easy to make with an analog ...

He had a MPX5010 analog pressure sensor lying around, but could not interface it directly with the DH-100. He found a Picaxe M20 in his parts bin and decided this was a good way to build his first ...

As more sensors and actuators are added into electronic devices, pressure is growing to more seamlessly move data seamlessly back and forth between analog and digital circuitry. Analog and digital ...
