Here is a useful circuit for Arduino lovers and experimenters. It is a simple digital voltmeter, which can safely measure input dc voltages in 0 to 30V range. The Arduino board can be powered from a ...

I had cause to have a closer look at some Arduino inputs – it is that fascinating weather station again. It transpires that some Arduino inputs are better at tolerating slowly-changing inputs than ...

Using DSO138 Smart Oscilloscope for Testing Arduino Signals The DSO138 smart oscilloscope is a compact and affordable tool for signal visualization. It can be used to test and debug signals generated ...
