The 4-20 mA Current Loop

The I/O capabilities built into most microcontrollers make it easy to measure the analog world. Say you want to build a data logger for temperature. All you need to do is get some kind of sensor that has a linear voltage output that represents the temperature range you need to monitor — zero to five volts representing 0° to 100°C, perhaps. 50 more words

Moon Rise

There was a Full Moon last week. A line of trees along a creek east of our house hides the horizon so we do not get to see moon-rises (or sun-rises.) I happened to look out the window when the Moon was high in the trees. 81 more words
