Detectors in science In order to study anything in science, you must first be able to detect it. The most interesting things, of course, are those that we can detect with our own senses. We then use devices to amplify
Digispark: We set out to build a little brother to the wonderful Arduino line of development boards – we were tired of leaving our valuable Arduino’s behind in projects, or worse, ripping apart old projects to build new ones! We also felt
Normally smartphone events are tightly coupled to your phone device itself. When your cell phone is ringing, your phone speaker plays a ringtone. When you get a new text message, your phone displays it on its screen. Wouldn’t it be
One of the more interesting aspects of Arduino’s is taking them with you. Now I don’t mean putting a bunch of parts in a small box and sticking it in your pocket, but actually integrating the circuits, conductive thread,
We continue with the project by building the temperature sensor module. We are using our favorite, the Dallas DS18B20 digital sensor. It uses one pin to communicate with the Arduino, along with +5vdc and Gnd. We add a 4.7k resistor
After looking at the documentation on our White Rogers thermostat, it looks like we can simplify the operation as such: Now this would be fine, if we were just interested in manual control, but we actually want this to be
