Reverse polarity is one of the most common causes of circuit failure, from hobby projects to industrial systems. The good news is that a well-designed reverse polarity protection using MOSFET ...

I love the Pi, but it's not always the best tool for the job.

They're reference designs for a reason.

Jennifer Carpenter’s drug addiction explains why she stole schoolchildren’s medications to use for herself. But in no way does it excuse it. And on May 5 in Fairfax County Circuit Court, this former ...

Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, and turning off when the sensor is released. The testing of the keys ...

Although off-the-shelf breadboards are plentiful and cheap, they almost always seem to use the same basic design. Although you can clumsily reassemble most of them by removing the voltage rail ...
